Andy, your mention of NXT panels has led me on a long journey through some of the most bizzare speakers I've ever seen. I can't seem to actually find anyone who sells what I need, and the NXT website is just terrible (it has no information to speak of), but I've really enjoyed seeing these incredible ideas. From picture speakers to projection screen speakers to ceiling tiles (just what I'm looking for), these are just crazy.

However, I think this takes the cake
