draw a new one
Created by Carnegie Mellon student Billy Keyes, Co.Design says that SketchSynth uses a webcam to detect shapes, and a projector to generate the interactive elements. In its current form you an create buttons, toggles and sliders by drawing circles, rectangles and lines, respectively.
And as awesome a this already looks, it’s still in its infancy. There’s plenty of room for improvement and added features. Maybe someday we’ll be drawing 10-string guitars or something absurd like that. [SketchSynth via Co.Design]
