Like a Swiss Army Knife, This Wooden Shelf Folds Out to Reveal Multiple Functions

Why hang up multiple shelves for keys, knick knacks and whatever else, when you can combine them all into one supershelf? Dubbed the "Mexican Army Shelf", this multi-faceted shelf concept attempts to answer that question.

Designed by students at Ludens, a Mexican design school, the shelf has about 4 layers, which reveal places to hang clothing, store coins, write notes or stash your keys. There are even fold out sections that reveal a mirror and cupholders. This is clearly still a concept, and while it seems neat, I could also see this thing getting chaotic if you tried to use it for too many things at once.
