Zach's wubbulous structures

Zach got a marble run for his birthday and he has been playing with it almost everyday. He builds such wonderful structures that remind me of the Wubbulous World of Dr Seuss. Major spans and cantilevers. Very fantastical! He builds these structures all on his own and ravels in the challenge to build higher and more wubbulous ones. PLUS they always work! Marbles run down on their predetermined tracks from top to bottom without being stuck.

Take a look!
