Amazing to stumble across this thread, as PMMA and its molecular structure were just on the whiteboard behind me (before it got taken over by World Series baseball). It keeps coming up in the nanoscale materials literature I've been researching over-and-over again, and now on CodeProject (spooky!) It's like the hot buzzword, the sort of thing they talk about over cocktail parties in movies like the Graduate, but the word is not "Plastics" -- it's "Poly(methyl methacrylate."

I think dial-up networking users who are backing up their folders to these cloud storage providers are downright envious.
