To Humus:
nVidia will be the only vendor with 3.0 shader model support for about a year. So, you have no choice

for existing sh demos see:
http://www.paulsprojects.net/opengl/sh/sh.html
http://www.donw.co.uk/
and the directx9 sdk (summer update)

btw: in the gritty details papers the recurrence relation for sh rotation in the appendix is wrong. But with the demo at www.donw.co.uk comes rotation code which uses the ( almost? ) correct version. Implementing the general sh rotation is really a pain in the ass...

Thanks for all suggestions. My list of demo ideas is filling up.

Regarding spherical harmonics, I've been thinking of learning that technique, it seems very cool. However, I haven't found any good resource that explains it in a clear and straightforward way. Anyone have a good link?

Darren,
you need relatively new drivers and you need to do a registry hack.
