The UniJoystiCle is a unicycle simulator. It allows you to use your play unicycle video games using a real unicycle.
It requires the UniJoystiCle device and a Commodore 64.
You have to attach your iPhone into your unicycle pedal, and just pedal! The iPhone will send your movements to the Commodore 64 using WiFi.
Alternatively, you can set the iPhone in "D-pad" mode, and use it to play any kind of Commodore 64 games. Or put it in "C= Home" mode and use it dim lights. Or put in "Gyruss" mode and use it to generate random music. Or put it in "Commando" mode and control the two joysticks at the same time.
