Wow, this is pretty impressive, there is a WIP port of Q3A to the Nokia N900 using the accelerometers to control movement and there are some videos up to see using the TV-out on the phone:

Someone even video’d a multi-player demo at the Maemo summit.. 😉

It’s not publicly available (for the moment at least) from what I can tell, a comment on YouTube says:

Currently not (“yet” I’d guess) – but remember that this is just a work in progress / feasability study – this is only a developer version that got distributed over the weekend during the Maemo Summit 2009 in Amsterdam.

Still, looks fun! 🙂
