Ivy by Dutch designer Joris Laaman (who had designed a decorative radiator made of concrete and is one of the editors of the gorgeous re-luct) is a kind of lingerie for the wall.

The seven elements that compose Ivy can be combined in every single way. Ivy is made out of polyester concrete, a material used for sports climbing grips. And like these the Ivy pieces are attached to the wall with Allen-screws.
