A couple months ago I hacked together a demo of [Chipmunk Physics](http://wiki.slembcke.net/main/published/Chipmunk) engine running on the iPhone using the unofficial SDK. It shows the standard Chipmunk demos, but also it reads in accelerometer data using the method described on the [Medallia blog](http://blog.medallia.com/2007/08/iphone_accelerometer_source_co.html).

For the most part it was a fairly simple translation from standard OpenGL to the OpenGL ES the iPhone uses. If anyone is interested in the source code, let me know and I’ll see if I can find it… *edit: source is posted. see below*

[iPhone Chipmunk Physics demo application](http://tlrobinson.net/misc/iphone_chipmunk_physics/chipmunk_demos.tar.gz) – run from the command line (either using MobileTerminal.app or over ssh), only tested on iPhone software 1.0.2.

*Update: [the source](http://tlrobinson.net/projects/iphone/Chipmunk-iPhone.tar.gz) – this is just modified from the original Chipmunk Physics demo, so the original license applies. I can’t support this at all, so you’re on your own. I believe I used the hacked iPhone toolchain version 2 (or 3?), so you may have to edit the Makefile if you have a different version or installed it somewhere other than /usr/local/bin/.*
