yea i ran across tat the other day when i was looking at all the new stuff thet have in stock.... it's not the only one either, they have a gothic version that sits on a table, instead of a backpack. if i were GC, i'd stop getting these weird devices and invest in RooR's!
EDIT
http://medusepipes.com/main.php here is the website for the creator of the piece, oddly enough, not even they have diagrams for how to use it. I'm sure glad I'm not buying it or else i'd be pissed, not knowing how to use the damn thing!
