This is probably one of the coolest things we have ever seen: The Austin Bike Zoo. These beautiful, unique, hand-built creatures are powered by pedaling and were created by Jeremy Rosen, a mechanical engineering graduate of UT Austin. The creatures were created for use at parties, festivals, events… can you imagine the rattlesnake or a bevy of butterflies at your next family reunion?! Take a look at some of the cool creatures. Best of all, they light up at night! Learn more at the Austin Bike Zoo blog.
