More progress...Just posted a screenshot showing some progress at last! I've decided that my game is going to be based around the idea of ironing clothes. Apologies if anyone was already doing this, but with one thing and another I've not been able to keep up with what everyone else is doing as much as I'd have liked.
The next problem I'm going to have is finding a way to add wrinkles to my shirt... I think I might be having a look at the bump mapping example in the Pygame Code Repository!
