I'm working on some games, but those are going to take some time to complete. In the meantime, I have this fun video App you might be interested in, Mosaiplay.

Mosaiplay lets you play multiple videos at once in customizable grid layouts. Build your wall from 8 presets or design your own, mix in clock and RSS widgets, save full compositions, and control every tile independently. Supports all major video formats. No internet required.

Do it your way, and make it spicy :)
