See this wall of colorful squares? It's actually a concept design consisting of a bunch of small triangular panels which can be spun 'round on whim to change the way your room looks. Or to spell out naughty things.

Ok, so the concept photos only spell out "S-E-X" which won't make too many people giggle and blush, but just imagine the potential ways you could satisfy your inner decorating perv. And even without that silliness, it's still a pretty neat thought that you could completely change the look of a room without having to reach for the paint buckets. [Yanko Design]
