Years ago, I had this idea for a virtual fish tank. It would have five LCD displays (possibly touch screen) and a 3D rendering of fish inside. Each face of the cube would display the corresponding camera angle. For years that idea sat in a notebook, because I had no idea how to actually do it, and was making it way harder than it had to be. (I really have no idea how to do anything more complex than a cube in OpenGL.)
Well, it turns out someone at the University of British Columbia had the same idea, and built pCubee, a perspective corrected display box.
At least it was hard to do.
Fuck the iPad. I want this.
