Who hasn't thought of pairing an off-the-shelf R/C Focus Rally Car with a camera phone? Designed for surveillance purposes, the R/C car uses a camera phone hooked up to the on-board electronics, allowing the user to pilot the vehicle from their very own phone. With this setup you could see what's going on in your neighborhood from the comfort of a cafe in Vienna. Or the other way around.

Though the military uses vehicles like this for destroying bombs and surveying territory, this is a relatively cheap and simple solution for someone who needs to spy on others. We just hope that the designer keeps it away from this guy. [PhysOrg]
