Tetris Shelves

BraveSpaceDesign's Tetris Shelves.

Gizmodo posted a picture and a little text about BraveSpaceDesign‘s Tetris Shelves. More from BraveSpaceDesign can be seen in this post at Land+Living.

They’re all the standard Tetris shapes constructed of walnut and ash. My previous attempts at cabinet making were miserable failures, but considering these shelves cost seven large — yes, $7,000 — it’s more likely that I’ll be making my own than buying them.

Question, though, am I violating copyright/trademark/patent law if I built my own for personal use? What about if I baked cookies?
