I came across this website this evening:

Link: ENESS - interactive design, public installations, 3D software development from Melbourne, Australia

They carry some products on the site [particularly tiles] which might interest some here:

I would not put them up in my house I just thought they were original anough to post here.

Also have a look at Whiteboard Pong [Not a product supplied by them]
