Japanese designer nosigner created a series of triangle, square and rhombus-shaped desk organizers for the Tokushima Wood-Bamboo Workers Association. What you're looking at in the photo is called, *Triangle / Square / Rhombus.* Each individual small box is magnetic, allowing you to create your own wild pencil/pen holder!
Other than saying they're magnetic, the Spoon & Tomago design blog doesn't say how the parts are connected. I guess we'll have to spend the 2,000 – 5,000 yen ($200-$500) to find out.
