Frantically wave your hands at your computer with a purpose using the Leap by Leap Motion ($70). The USB stick, when connected, creates four cubic feet of virtual space to perform all kinds of Minority Report-type hand gestures. You can even link several Leaps together to create a giant virtual workspace, where you control and manipulate virtual objects like the virtual god of virtuality. For the tech savvy (read: NERRRD), the Leap works on anything with an onboard computer, and its SDK allows for the creation of Leap compatibility apps. Suspiciously, Leap Motion isn’t disclosing information on the Leap’s specifics, so one can only assume they acquired this tech from some sort of satanic blood pact.
