You would so hate my room, half of the computer parts are on the floor.
Its fine, Ive never damaged any one of them from doing it. (I havent even trod on one :-D )
Some things that are on the floor in my room at the moment:
Cyberstorm PPC Card
Emplant Card
Powerflyer
A1000 Motherboard
loads of CD's
yesterdays cloths... etc etc.
Also they put it on the carpet because its a good background, better than some patterned table or such like.
I think those pictures are well taken
