I will soon be doing a Lego marathon in aid of the Brian Munro Cancer Fighting Fund. I will be building for 20 hours non-stop, in an attempt to complete the 3,803-piece Death Star in one sitting. The date is not yet finalised, but the whole thing will be live streamed. Pledge your sponsorship (either an amount per hour or a lump sum) as a comment by emailing me, and I'll let you know details of watching (optional!) and paying up.

This video shows what's involved: http://youtu.be/rLq-bOk809s
