Tobias Eichenwald wrote last week to give me an early look at his company's new controller, named Flow. Like a 3D mouse, it is designed to work with your existing 2D mouse. Unlike the 3D mice from, say, 3Dconnexion, this one has no buttons.
(Important: this input device is not available yet, and is dependent on funding from an IndieGOGO campaign that begins today.)
The puck-like device is used by rotating it and tapping on areas of the white top. It connects through Bluetooth (not available on most desktops, however), has an API, and can be customized by end users for specific applications -- 30 at last count, including Rhino and AutoCAD. It is expected to ship in June, be manufactured in Germany, with early backers paying as little as $79.
The best thing is to visit the Web page and see how it works through videos. https://www.indiegogo.com/project/preview/ec7eaad9
