Ever wish your wall could shout "Great Scott!" without actually shouting? This word art poster is like a visual time warp, crammed full of folks, locales, and gizmos from a beloved set of flicks about a teenager and his eccentric older pal zipping through the ages. You'll spot monikers of the perpetually put-upon bully, the quirky inventor, the object of the protagonist's affection, and even that four-wheeled contraption that made history (and altered it a few times). It's a fantastic conversation starter for anyone who knows their gigawatts from their plutonium. Just gazing at it might make you want to check your mailbox for a letter from the past... or the future!
