Ooh, I'm watching very carefully... I'm finally starting my Flash retheme this Summer as well. Thanks for all the great pics! My theme is Megaman (taking art/music from the first 5 NES games) and I'm taking a lot of inspiration from that Flash Gordon to Ghostbusters retheme from a few years back. Hopefully I will keep track of it at http://megamanpinball.blogspot.com/ (but nothing there yet... need to get off my butt and get going on it).
Good luck with the project!
