Re: Nintendo wii console
The Wiimote works on the PS3 (albeit on Linux and as a gyroscopic mouse). So does a wired 360 controller (again, on Linux with the correct drivers).
I had an article somewhere about a British company who were developing similar controllers with different technology. The great thing about these is, though, that they're wireless with USB receivers, and they're shaped -= so if you're playing a bat and ball game, you use the bat (I think you get a little thing that you add the shaped extension to), and so on.
I don't know if they got anywhere with them (the article's from early last year), but it sounded pretty fun. And if they can get the developers behind them, well, looks like the Wii might just become some last-gen hardware with a few fun little games.
