Tensor Voting is the name of this clever thing from Swiss designer Guilio Parini. It is a wall sculpture that serves as a customizable storage system. It arrives to you as a pile of rods and fasteners; you decide on a shape and build a skeletal system of your choice. Tensor Voting allows to play with different geometric configurations, so you can really let your artistic flag fly. As a shelving unit this model can withstand a reasonable number of books and small items.
