Oskar. Connectivity.

My friend Oskar van Deventer is one of the modern world's greatest puzzle designers. On the one hand, he pretty much just designs mazes. But these are mazes only in the generic sense that a maze requires you to move from one state to another.

While catching up with Mathpuzzle, I was delighted to see that an Oskar puzzle is now a 30x30x45cm public sculpture. You'll have to just go to the site and scroll down to "Material Added September 11, 2005." Years on the web and Ed doesn't understand permalinks.
