I have a thing for design. I used to go to the New York Gift Show for my old job, and usually the coolest stuff there was either in the "Handmade" section, (mostly art glass and metalwork) and the "Accent on Design" section.
There's more stuff at the inhabitat website. Look at the "Tetris Shelving". (via)
You can also find similar cool stuff at MoCo Loco
