Modular shelving never ceases to interest me (see Yube Cubes and Way Basics) – but these might take the cake. Combination shelving and art piece, Ivy by Paris Lowitz is a system designed to "grow" on your wall as you see fit.
The system includes three different pieces that can be configured and reconfigured in an endless array of combinations. I love the organic yet streamlined forms.
Alas, Ivy is just a concept right now but I hope it gets put into production someday!
