Sean Murphy has posted a blog detailing the charity bike ride he and his family took part in! You can read his story, which includes pictures, here... if you're interested in donating money for the cause (there's still time!), you can read all the details here. Sean was also kind enough to send along some details on what he'll be working on in terms of wallpapers:
I messed around with the Shrike model yesterday a bit, and am now possessed of an urge to do something I've wanted to do for a while: namely, rebuild the sucker. The model I've got is the old NURBS model I built for the game, but there are things about it I've never liked - especially in the texture area. I'm considering rebuilding it in polygons (which would, incidentally, make it ideal for use in any 3d package, not just maya), and adding more detail and touching up the rushed-over areas. It's kind of an old itch I've never gotten around to scratching. I think it'd be neat, and would result in some super-spiff high quality models. Of course, that'd slow down delivery of wallpapers but I think it'd be worth it, and I'd of course provide updates on how it's going to prove that I'm not slacking off!
