Wow! Your Web of Spiderman skins keeps growing! Keep it up and you could one day be one of the Ultimate skinners 
Haha! I like that one (though I have to admit I don't much like the Ultimate series anymore). And when you wrote skinners, for a second I thought it said spinners (like web-shooters!).
Don't worry about the model. I know the PS2 models are limited, and there are many custom meshes and models that give you WAAAY more skinning posibilities. It would be selfish to expect you to work ONLY on PS2 models when you'd be very much limited. Don't beat your head over it, just keep doing your stuff. You're among the best there is at what you do, and what you do is very nice.
And I don't think we're running on such limited material, Spidey has been featured in a ridiculous amount of comics. There's still the Marvel Team-Up, in which Spidey joined forces with other heroes. (That one would definetely go for the Hackathon).
I lol'd with DeeDooo's witty use of the material.
Thanks. As for what's left, you make a good point, there is an abundance of them, but most aren't as well known.
Sweet, no problem... with skins this awesome, I can be patient!
I like the Ends of the Earth Armor for Spider-Man as well... spectacular job! 
Can't wait to dish out some pain in the Mark VI armor!
Aw nuts, I should have thought of that. Good one man.
btw Hyper, if you ever get the chance and or you ever want to. How about taking a crack at the Bleeding Edge Iron Man suit?
here are some pics if you're ever interested.

Yeah anonymouspunk, I like that armor as well.. I think Hyper can do it justice! 
Thank you guys! What's left is 1, 5, 7, WM, and that custom Iron Patriot. Unless I can find a good base, I'll skip 1. 5 (if you don't already know) is that briefcase portable armor that was red and silver. I'll probably concentrate on War Machine next though. I have to mention though, there's a bunch of text labels on the War Machine armor in the movie, so I can't include those. (They'll get flipped on one of the sides.)
I'll put Bleeding Edge into the possible ideas section, but I'm thinking I'll do a movie-style Bleeding Edge if I do it. (Although, it's already pretty close to that anyway.)
