The Tomy Q-Steer Choro-Q is a tiny remote controlled car that you can guide with any IR compatible device, including your cell phone. It measures 1.5 inches long (40mm) and can be used to zip along your harwood floors.
Implications - In an era in which phones control our lives, it is not surprising to see something completely unrelated to a phone being controlled by one. Adding an extra dash of novelty and modernity to a traditional item like a toy car is one of the ways in which a brand can respin their products for the digital consumer. It probably won't be long before other items -- maybe even real cars -- will be controlled by external devices.
