very cool stuff, i never seen a joust cocktail that is a interesting design although somewhat larger then what you expect in a cocktail.
It is, by far, the most comfortable cocktail I have ever played on (I was fortunate enough to pick one up some years back ... it is one of my grails). The angle of the monitor doesn't require you to hunch over to play.
The design was also patented and, IIRC, joymonkey once linked to the patent documentation, but I'll be damned if I can find it!
