ESP32 iPhone Agent uses a tiny board to receive iPhone screen mirroring and act as a USB mouse and keyboard. An AI app on that same phone directs taps and swipes, such as setting an alarm. No separate computer is needed at runtime.

Strange Inventions Lab turned an iPhone 13 Pro case into a miniature marble machine. The case contains a track and an Archimedes-screw lift, so tilting the phone sends a ball through the course and raises it for another lap.

The creator describes it as an experimental design that needs a fairly specific angle and can occasionally jam. It uses 19 screws and 12 ball bearings to add a complete mechanical toy to an object normally designed to stay thin and unobtrusive.
