Somebody has went through the effort to get OS X Cheetah running on the Wii. It is pretty basically currently and is currently lacking a lot of support for the Wii's hardware, but still impressive. I wonder if something is possible on the
PS3 or the Xbox 360 as they use G5 based CPUs and I believe they had similar changes done to them compared to the Wii's Broadway CPU. If you are interested here is the code for the project: https://github.com/bryankeller/wiiMac

Born to Tux, Forced to Windows.

Very cool! Thanks for sharing. I read a bit of the github page and this seems like a very recent project and is still being updated to this day.
