Got a Raspberry Pi (sponsored by Nokia through the QtonPi project, thanks!). Was pretty easy to get running. For starters I ported my 4kb demo “San Angeles Observation” to run on it. I used the VBO-enhanced code from Chromium source tree, so it runs much better than the original OpenGL ES port. :)

Here’s direct download link to runnable binary: Download .tar.gz – Tested to be runnable with the Raspbian wheezy distribution (2012-08-16 build).
Edit: As noted in the comments, if you can’t run it, try to change your memory split to 192/64 or 128/128 using raspi-config.
