There are very few products from the demoscene that are available on Mac OSX.
In preparation for some more challenging ports of old demoscene products across to OSX I thought I would start with one of my own productions. Unfortunately, I historically used DirectX, but I did do one OpenGL production, Trip! for Syntax 2007. And now, the Mac OSX (Intel) port of Trip! for Syntax 2007, unfortunately nowhere near 4k anymore. (Warning: Plenty of black/white flashes, the illusions will only work if you stare at the center of the screen)
