Shrewsbury on Sunday, and after the traditional Saturday night of eating, drinking and drawing on tablecloths, there is one more gallery opening event. Professor Colin Pillinger, the architect of Beagle 2, the Mars Lander, has a personal selection of cartoons titled Science Friction at the Shrewsbury Museum and Art Gallery. After that, all the cartoonists gather at the Bear Steps Gallery for a meet-and-greet with the public, before heading back home to their drawing boards.

Shrewsbury’s venerable Bear Steps Gallery this year houses the Boffination exhibition. The venue is packed to its ancient rafters with high quality jokes on the subject of science and nature which the festival cartoonists will be only too pleased to flog to you for home display.
