GoldieBlox, Rube Goldberg, & Beastie Boys "Princess Machine"

This video is so beyond awesome that it deserves its own blog post.  I may or may not have shed a few tears watching it.  Keep on kicking butt, GoldieBlox. We need you.

(Edit: I've replaced the original video with an update after it was removed due to controversy surrounding the use of the Beastie Boys' song.)
