Of course

Well this super-steep 45-degree angle downhill mountain parkour course isn't really parkour in the usual sense -- closer to annoying and painful knee torture with some vertigo thrown in.




Unrelated, really, this Rube Goldberg machine not only does its normal Goldbergian thing but plays out a heartwarming tale of two colored balls who have to rescue their trapped brother. Potential fodder for a Hollywood blockbuster. (ballbuster?)




And this "robotic loop" toy train track is sort of the opposite.
