Codify for iPad: simple particle engine in 30 minutes
Channel: phyces
Date: 2011-10-27

Very simple to develop in. Took me about 30 minutes, looking forward to future improvements. 

The coding is done in LUA scripting language, and everything can be run right away. It uses opengl-like calls for drawing.
