Multi-Touch Spherical Display DIY

I want one!  It’s a multi-touch spherical display that you can make for around $1,000.  Oddly enough for such a high tech device, it’s got a bit of a steampunk vibe to it.  The first example they use is the obvious Google Earth example, but they do show using it in other contexts.  I’m not convinced the photo viewer or music making device really needs a globe surface.  If you’re interested in making your own, the directions for building one can be found here.  WARNING: The directions aren’t exactly the simplest to follow and I’d imagine there’s a lot of winging it involved.
