After the presentation last year about using the Nintendo Wii remote for giving presentations we are this year taking it to second base !
For all speakers we will provide wiimotes and bluetooth dongles in all conference rooms. We also created a CentOS-based LiveCD with various presentation software and WiiPresent. With a single click you can connect your wiimote to your system to start applications and control your mouse.
The advantage when giving presentations is that you get force feedback (rumble!) every 10 minutes and you can see time progress on the wiimote leds, button combinations allow to switch workspaces or blank screen and the screensaver is automatically disabled.
