Ben Heckendorn, designer of the Xbox and Wii laptops, has built a prototype of a single-handed, configurable console controller. This wireless controller not only puts all the functions of a traditional controller under a single hand, but each control pad is removable and can be swapped for right- and left-handed configurations.
A wireless PS2/PS3 version of the controller is currently in pre-production, and an Xbox 360 version is pending. For more information, check out Heckendorn’s announcement of the new controller.
