It took a while to sort out the perimeter on this one. Eventually the penny dropped once I saw how the left-hand side of the grid would work. I've got the source on my iPod somewhere, which helped a lot to finish the rest off!
A few very nice clues but I also haven't sorted out everything that's going on in the down clues, though I know what the instructions have to be. Also puzzled by that "9" in the top right corner. Still, overall a nice puzzle with a theme I enjoy a lot so thanks MynoT!
