It would be cool (maybe useful?) if there was an app that would create two screens from the Windows UI (one for the right eye and one for the left) using the window depth (z order) so that it would be steroscopic when preceieved, with real depth-preception depth.
It would be cool if the output from this app could be either a Blue/Red transparet overlay on one monitor (to use Blue/Red 3d glasses on) or output to two seperate monitors (VR glasses?). (do a search in fickr for Stereophotography, most of these you have to cross your eyes on, but you get the concept.) Windows has depth information about it's windows allready so the app should have all the information it needs.
I'm thinking the mouse would not sink down when travelling across "lower" windows.
Am I just a nerd or what? Anyone else think this would be cool?
