I learned another relevant fact about light and shadow tonight - notice the way the top disc on the cylinder is shaded more on the light side and gets lighter on the dark side, the lightest part being directly above the core shadow? It's all an optical illusion. Actually the top disc is uniformly lit all across - I scrunched my fingers up into a weird shape and covered the sides of the cylinder and it was just a flat disc, no shading at all on it!! It literally just looks darker or lighter in places relative to the values against it. That was a mind blower - like something off of Brain Games. I'm immensely glad I bought these little doohickeys!!
