This DIY Robot Is Better Than You at iPad Games

Piano Tiles 2 is a touch-based mobile game that's lots of fun, and also maddeningly difficult. A normal person probably plays for a few weeks, gets frustrated, and uninstalls it. Thankfully, YouTuber DenverFinn is not normal. For him, the obvious solution was to build a robot that slips over an iPad and acts like human hands, only better. An iPhone overhead films the game at 120 frames-per-second and sends visual input to a controller that knows to seek out the black keys and avoid the white spaces.
