I always found the bone scene in 2001 Space Odyssey striking. The moment humans discovered tools. It’s what separated us from other animals. Helped us evolve. And eventually create the motorcycle. Nice one neanderthals. On the flip side, if you’re not familiar with 2001, then this design is simply a wrench monkey. You pick.
