This is it: My masterpiece. My magnum opus.
I completed this over about seven weeks, from 11 December, 2008 (when I offered a preview image on my blog) to 31 January 2009. At a very rough estimate, I'd say I put at least 30 hours into it. The idea had been stewing at the back of my mind for maybe half a year before I finally had enough free time and energy (Summer holidays rule!) to do it.
I hope you have as much fun watching it as I had making it. At least it won't take as damn long.
