This cute  sideboard by Jesper Ståhl  for a Swedish brand Voice is based on a great idea - the size of the unit corresponds to an A0 paper size and then each of the doors or drawers are other smaller paper sizes down to A8.  Well it won´t work in the US, but still I found the idea pretty cool, especially for people who know their paper sizes:)  I wish they would do some other color combinations, as the green tone is not the greatest for me.
