Where are Mark and Mike?

Can you find Mark Kistler in the picture below? How about Mike (hint: Mike's friend Flash is looking over his shoulder). Can you find a man with a beard? Can you find a kid with his mouth hanging open? Can you find 500 wacky, happy art animals (hint: you'll find one if you look in a mirror!). And where's Waldo? (Okay, Waldo's not there, unless he's hidden behind the banner....)
