Well, the Bosch router I bought for my last DIY project would be rendered somewhat futile.
It sure looks cool, but I can't imagine trying to work with glass on a DIY project. It would have to be relatively thick glass as well, and the internals would have to be laid out quite nicely (somewhat eliminating the ability to use poly as well) since everyone gets to see them.
I did get a good laugh reading the new term they coined "super silent glass". Noisy glass sure wouldn't work as well.

I assume it's just really thick glass?
I remember Velodyne had a similar looking subwoofer once upon a time, though it was made from acrylic ...
