for a presentation I made a brief video of the virtual reality in action and because I believe in sharing I decided to put it up here as well. What you can see is my hand (cunningly disguised as a mouse) "running" on the treadmill through a T-Maze.
There is still room for improvement for contrast, colour (which mice can't see anyway), etc. but the basics seem to be ok.
Enjoy a fascinating journey through a magical world with stripey and dotted walls. I wonder if mice could learn to play 1st-person Pacman...
