Google gave the Shweeb $1,000,000.
At Velocity Valley in Rotorua, New Zealand, there's the Shweeb: a pedal-powered monorail. It's a fun ride: but in 2010, Google gave it a million dollars as a potential "future of transit."

At the Department of Collective Behaviour, part of the Max Planck Institute of Animal Behavior, researchers are putting locusts into simulated worlds, both virtual and physical, in the hope that they can figure out how devastating swarms form and move.

This town throws pennies at people. They hurt.
The Honiton Hot Pennies ceremony is the result of 800 years of tradition: from when rich people would entertain themselves by throwing scalding-hot pennies onto the poor people below. These days, it's a bit less dangerous - but only a bit.
