IR-enabled cell phone strap race cars.

If you like racing cars but can't afford a Ferrari, you might consider getting one of these cute little cell phone strappies. You can remote control them via infrared from the Fairladyz tire pictured above (two of the tire spoke gaps are actually forward and reverse controls), or you can maneuver your bad boy using an IR-enabled DoCoMo. Available for less than 1000 yen here.
