Flow is a wireless, touch-free gesture-based controller that aims to replace mouse and keyboard in many applications. It's just been funded in a very successful Indiegogo campaign, receiving more than five times the designers' goal of $50,000.
The Flow is fully programmable, and can consequently be targeted for CAD, graphics design, video and music editing, and other applications.
The Flow controller has earned a lot of feature coverage in the tech press; TechCrunch, Engadget, and gizmag, just to name a few. Flow should be shipping this summer.
