iGrip Handheld Keyboard/Trackball

This is by no means an immersive input device, but I'm posting the link in case it may be useful to some of you, either as a typing solution whilst immersed, or simply because it, being a keyboard, has quite a few buttons. And it's got a trackball.

I can answer certain questions about the device, though I have yet to fully train myself with it. The learning curve isn't bad, I'm just lazy.

I didn't see a rule about this, but just in case: I sent them an email asking for permission to leave these images hotlinked, and Mike Willner, the device's inventor, happily approved.
