The Diana's grassy roof isn't open to most people yet, but Spectrum's Adrienne Penaloza was up there with her architecture class earlier today. ("We were up there testing devices we made to melt ice or keep it solid for an independently determined length of time. Literally sat there and watched ice melt for 2.5 hours.") She managed to get some great photos of the roof, which looks pretty cool. Photos—with Adrienne's captions—after the jump.
