I'm the developer behind the Quake 3 demo at Maemo Summit yesterday. Currently there are no packages or sources online yet, but I am going to try to get the source onto Garage as soon as possible (takes ~72 hours to register a project.)

Quim already posted some information, and hopefully we'll get the video online soon. I've attached the slides, although they are nowhere near as interesting as the video.

As far as performance goes, I usually cap it to 30 fps due to battery life, but the (currently not very optimized) code can hit between 30-60 fps in some places.

I'm sure a lot of you are looking forward to getting the package and hopefully some of you hacking on the code, too. You do need to have a legal copy of the Quake 3 data files, however, as it would be illegal for me to distribute them.

P.S. Thanks for all the positive comments.
