That second one is a really tricky maze, especially with start and finish unlabelled; or is it a dot-to-dot w/o numbers?
Ironically (in light of charlatan's phone table tale) I did something similar to my first telephone with a sharpie, only using short, squiggly "s" shapes instead of dots. Made it less boring than plain white.
Edit: sometimes I'm not as funny as I think I am.
