Fun idea with the mural - 2D/3D/2D. Kind of a visual pun. Yep, hard drives should never click at you (other than the faint sound of head loads) - that's the head crashing (or trying to) into the surface of the media. As a PC consultant i sometimes show up with a stethescope around my neck for listening to drives, and lightening the mood a bit. Good that you do serious backups - so few people do enough of that.
