There are more styles of flash drives on the market than you can shake a stick at. Some of them are weird too. I have seen flash drives that look like food and all manner of other weird designs.
These Flash Rods flash drives are cool and very interesting. The things are handmade and start life as a Hot Wheels car you might collect or your kid might play with.
The car is opened up and a flash drive with 4GB of storage is wedged inside. The rear of the car is cut to let the USB connector stick out. You can pick one up in a bunch of different styles for $25.
