It is probably a 20 year old AllGlass!  A good WI company by the way.  I posted once before (http://nantz.org/Blog/tabid/57/EntryID/554/Default.aspx) about a unique fish tank that lets you pet your fish (http://www.ohgizmo.com/2007/03/26/pet-your-fish/).  Now I see one in a deep fryer? (http://www.ohgizmo.com/2007/03/29/japanese-deep-fryer-has-aquarium-within/) and one made of ice (http://www.ohgizmo.com/2007/07/03/ice-fish-tank/).  AllIce?  Then there is the MacG4 fish tank (http://www.boingboing.net/2003/11/19/g4_cube_fishtank.html).  But my favorite is the hamster-tunnell-like aquarium (http://www.makezine.com/blog/archive/2007/01/fish_swim_aroun.html and http://blog.wired.com/tableofmalcontents/2007/01/build_a_better_.html).  I also saw something like this in a restaurant once.
