Dial "R" for Retro

Retro Phone Handset Geek Toys Yeah, we know all about those bluetooth headsets for cell phones, but forget that stuff! We have here the latest development in cell phone technology and it's a big hunk of beautiful plastic. An accessory for your phone that you can really grab onto. Something with heft and that good-old-American solid construction feel - like a 1972 Cadillac. The Retro Phone Handset is a new production replica of the Western Electric 500-series model, which was the classic phone handset for several decades. It's been slightly modified to work with the headset jack of most cell phones (or via a "hands free" adapter kit, sold elsewhere). Just plug-in and dial - or for added effect, put your cell phone in your pant's pocket - then it looks like you're talking on a phone connected to... well, who knows? Cell Phone Accesories

Easier than biking with a boombox on your shoulder

Universal Bike Mounted Gadget Holder

Back in the day, if you wanted to rule the neighborhood, you only had one option. You had to shove some C batteries in your boombox, pop in your favorite cassette, and balance that bad boy precariously on your shoulder while you cruised the neighborhood on your Huffy. That is, until that old bag on the corner called your parents and got you grounded again. Or (as our moms were wont to do) your C batteries suddenly went "missing." D'oh. But you're grown up now, and all you want is a way to safely attach your favorite gadget to your bicycle for those long rides. Sure, an armband works, but you'll kill yourself trying to see the screen. The Universal Bike Mounted Gadget Holder installs without any tools and holds just about any device (see list below). The 360 degree swivel tip allows you to position your device at any angle, landscape or portrait position. Its vibration free design makes it absolutely quake-proof, so you can view your gadget's screen clearly even if the road is bumpy. Because we know there are a few of you out there with a neuron deficiency, here are some warnings: Cycling with earphones on is a bad idea. You can't hear cars, or anything else for that matter. The Universal Bike Mounted Gadget Holder is not designed for use with extreme or aggressive bike riding. Watching a screen instead of watching the road can result in injury. Don't text and ride, okay? Oh, and by "bike" we mean "bicycle," not motorcycle. This ends the very un-fun paragraph of warnings. Product Specifications •Securely holds your mobile device on the handlebars of your bicycle •Suitable for most mp3 players, iPods, iPhones, PDAs, GPS devices, and mobile phones •Adjustable to the perfect angle, portrait or landscape •Vibration free, quake-proof design •Lightweight and high quality construction •Fits handlebars with a 22-32mm diameter •Installs quickly and easily without screws or tools

Zelda Ocarina

Zelda Ocarina Geek Toys While spelunking in the basement at the ThinkGeek headquarters we met a fairy girl handing out bright blue Ocarinas. She mumbled some warning about the end of the world, deku nuts and the tri-force but we were all too busy to notice. Later some employees found that during long afternoon meetings they could summon a galloping horse just by playing the correct melody on their ocarina. But then Ganon burst in and the jig was up... fortunately for you we stashed away a few of these completely playable Ocarina flutes to spend your hard earned rupees on.Best Gadgets

Dr. Timmy popped one in his mouth and realized he had discovered something amazing: the hottest balls he'd ever had in his monkey mouth.

Force point!

Star Wars Darth Vader Lightsaber Laser Pointer Best Gadgets A long time ago in a galaxy far, far away… some bad ass dudes fought with laser swords called Lightsabers. The Lightsaber Laser Pointers are roughly one third scale versions of the Lightsaber hilts carried by the Sith lord Darth Vader. Not only that, they double as red dot laser pointers. Laser pointers are just as useful as the force. They are perfect if you are teaching a class and need to point out the important equation that is written on the board. It is super fun to make your pets chase the dot around. And, just like a Lightsaber, it can cut through enemies like butter. (Well, maybe not...) The Lightsaber Laser Pointers are fully functional red dot lasers and super stylish mini Lightsaber replicas.Gadget for geeks

Compelling Spherical Distraction Contraption

Perplexus Geek Toys Have puzzles gone passé? With the advent and subsequent mainstreaming of videogames caused physical toys to go by the wayside? What do you get when you multiply six by nine? The answer to the first two questions is "No," and the last, "42." The proof that physical puzzles and toys haven't gone the way of the dodo is here. This little sphere contains a really cool three-dimensional maze with a ball bearing inside. Your job is to get the little ball from one end of the maze to the other. You've got to rotate the sphere through all three physical dimensions, and get our old friend gravity to pull the ball through loops, whorls, around corners, up walls, around pits, and across precipices to get from end to end. Don't worry, for training, there are places in the maze where you can pick up where you failed - call them "save-points" if you must. We tested the sphere ourselves, and found that even the most technically savvy and hardened gamer out there were significantly distracted by this little ball of fun. So, who said puzzles were passé?

Fizzy cake drink food beverage.

Fizzy Cupcake Drink Tablets Oberon and Titania dance in circles, fight often, and sometimes mess with the affairs of mortals. One thing they can both agree on, however, is that the only drink worth drinking is Cupcake Juice (it's the real reason why cupcakes are called fairy cakes in some locals).

Always know your way out

ExiTool Automotive Rescue Tool

Copywriter monkey would like to make a confession. She's deathly afraid of dungeon crawls. She's pretty sure it all started back in the days of EverQuest, when she enjoyed tearing across Norrath at the speed of sound with her wood elf bard. Being confined in an indoor zone with evil frogs and unable to run fast makes for one paranoid and neurotic bard. The idea of being trapped in a vehicle? Equally paranoia inducing. What could be worse than being trapped in a tiny vehicle with no way to get out? Oh yeah. Being trapped in a tiny vehicle sinking to the bottom of a lake. That is probably worse than death by froglok. Especially if you've forgotten the words to your Enduring Breath song...

Every driver has a panicked thought about being trapped in their car after an accident. What if you can't release a jammed seatbelt or can't reach the button to release it? What if the car is filling with water and you can't open the doors? The ExiTool fits on any standard seat belt with a simple folding clasp. It includes a seat belt cutter, designed to cut ONLY seat belts. Tiny fingers may TRY to get in there, but they can't! The tungsten carbide window breaker will easily and safely shatter side windows both on ground and under water so you can make your escape. The LED flashlight is great for shedding light on any situation, whether it's an emergency or an "emergency" like your cell phone falling in the void between the seats. If you have a vehicle, it needs an ExiTool. You may never need it, but if you do, you'll thank your Past Self for ordering one.

Beautiful and Puzzling

Geek Toys Frabjous Sculpture Puzzle The Frabjous Sculpture Puzzle is a sculpture and geometric assembly puzzle. The swirling geometric form is composed of thirty identical pieces. Mathematically, the planes of the shape are the face planes of a "great rhombic triacontahedron," a self-intersecting polyhedron with thirty rhombic faces. But the puzzle piece is a carefully designed subset of the rhombus that doesn't intersect copies of itself. Ok, so we copied most of that from the back of the Frabjous Sculpture Puzzle box. It's written by the sculpture's designer, George Hart (the Chief of Content at the Museum of Mathematics), and is very mathematical sounding. We think the Frabjous Sculpture Puzzle looks like a pretty flower. You will find it very challenging to put together (each piece is the same -sheesh!), but also very rewarding once it's completed. With your Frabjous Sculpture Puzzle assembled achievement unlocked, you will be propelled to the top of your social circle. Or, at least, you'll feel more awesome than you already are. Mathematical!

Now the enterprise crew knows how GLaDOS felt

Star Trek Potato Heads Like peanut butter and jelly or portals and cake, the marriage of Star Trek: The Original Series and Mr. Potato Head is a match for the ages.

SoundRacer Street Racing Engine Simulator

SoundRacer Street Racing Engine Simulator We grew up with Matchbox cars, driving tiny muscle cars across the bumpy terrain of our bedroom floors. Vroom vroom! Screeeeeeeeee! Vroom! We dreamed of the day when we would get our driver's license and be able to have our own V8 engine. Alas, the car we got was the one our parents had tired of, so Mom & Dad got the cool car while we got a hand-me-down with no AC. And now, we're too "responsible" for a sports car. That money went into a minivan to tote the kids to soccer practice or the dogs to agility competitions. But we still dream of turning the key in the ignition and hearing the thrilling sound of a powerful sports car engine. With SoundRacer, we can have the best of both worlds. Plug SoundRacer into your cigarette lighter and it will transform your car's boring engine sounds into the sweet roar of a much sexier car. Every action you take will affect SoundRacer: accelerate, decelerate, shift, cruise, or idle and SoundRacer will produce the appropriate sound. How does this magic work? After an initial calibration and a little fine tuning, the SoundRacer senses your engine's RPM by detecting the voltage increase in the cigarette lighter. It then produces the equivalent RPM sounds from a Shelby Mustang engine via your car stereo system. SoundRacer works great on most makes and models, but just to be sure, you can check the compatibility list here. Product Specifications •Makes your boring car sound like it has a Shelby Mustang V8 engine •Plug the SoundRacer into your cigarette lighter •Easy to calibrate and fine tune to work with your car •SoundRacer detects the RPM of your car using the voltage increase in the cigarette lighter and plays the appropriate sounds via your car stereo. •Works on most makes and models, but you can check the compatibility list here. •Note: SoundRacer does not work on hybrid or electric cars (yet).

Amoeba Dual Purpose Digital Microscope

Amoeba Dual Purpose Digital Microscope As wee geeks, we loved our science classes. Science was always fun and hands-on and related to the things we interacted with in our daily lives. Getting to play with the microscopes fell in the category of Best. Day. Ever. Using a microscope was like looking into a different world. We saw things that we didn't even knew existed - like amoebas! But we couldn't take the microscope home. And we had to share it with our lab partner, a kid with a purple spot on his left nostril, a clear sign of his grape-scented marker huffing habit. If only we had a microscope at home: we could have been studying science every night and every weekend. This dual purpose microscope is perfect for the home scientist. It features high powered specimen slide viewing and lower power to get a closer look at stamps, coins, and other small objects.

UV Monkey Before we went into space ourselves we first sent a few monkeys up there as a test. You know, check it out, see how it feels, bring back a detailed report and let us know how it worked out. These "brave" monkeys flew a number of missions to investigate the various biological effects of going into space, so we would have a better idea of what humans might experience. This small keyring gadget is like your own personal space monkey. The UV Monkey will assist you by checking UV levels so that you know when to charge solar devices - and when to protect your skin. Once exposed to sunlight, the center will change to different shades of purple to indicate increasing levels of UV light (darker means higher level of UV). The UV Monkey can indicate 4 different ranges of the UV Index (Index 1-2, Index 3-5, Index 6-8, Index 9-11).
