The accelerated-graphics bits in the ps3 are not exposed to the linux kernel, due to NDA/licensing/SuperSekritTypeStuff at Sony.

But, yes, post-reverse engineering, that would be nice. :-)

My understanding is that Sony expects to be able to make games for the PS3 hardware for the next decade or so. This seems fairly reasonable, given that they only stopped making games for the PS**ONE** two or three years ago. I still occasionally see them in stores, even.

There is a python script available to make the wiimotes act as a standard X11 mouse device (on linux, via /dev/input/mice); I hear that this works just fine. The link to instructions is here:

I bought a Wiimote and a Nunchuck (which has a couple extra buttons, trigger, a 'hat'-style analog joystick, and a few more accelerometers) a couple months ago with the intent of eventually doing some experimenting with them. No time available, yet.

[What I want is to be able to fly through large social network graphs in R... rendered in OpenGL. Is that too much to ask? :-)]
