This was designed for an invitation...could it be the logo for the upcoming movie?

Image #1: One of the many pieces of artwork shown in the Spider-Man video was this, which appears to be a design for a science lab. It could be either Doctor Octavius's laboratory (as director Raimi called the scientist-turned- supervillian known as "Doc Ock"); or the lab where the mutated spider that bites Peter is created; or something else we don't know of that exists in the forthcoming re-write.

And here is a sketch of the Spider-Man costume!
