Wiimote + beryl = wow!
Looks like Nintendo's Wii may play a more important role in the GNU/Linux world than we thought. According to this video it is possible to control beryl window manager using Wiimote. If this is possible then I imagine replacing a mouse completely might be possible as well, which is a big deal if people find it easier to interact with their computer using a "remote" rather than a mouse.
Mouse is, after all, pretty much tied to your desk while Wiimote is not. In the future when really huge screens become cheap, we may have a big computer screen on our wall, sit in a comfy sofa or even lie in the bed looking at this screen and doing everything on your computer remotely.
Well I guess it beats being nailed to the chair!
