## How do shapes fill space?

One of my main activities at the moment is making toys and materials for an interactive tilings and geometry exhibit at the this year’s Royal Society Summer Science Exhibition. The title is above. Lots of fun but also hard work. As I recently sent the flyer to the printer I thought it was a good time to annouce it here. So, if you are in London, why not visit us there from the 30th of June to the 4th of July.

The exhibit tells some of the story of tiling from ancient patterns through to hyperbolic and 4d geometry. You get to play with shapes and geometric toys and look at models and pictures. There will even be plenty of maths for those who insist.
