EGGs
For years now I've been obsessed with the noosphere, or the EGG project, which is now called the Global Consciousness Project. It's a set of random number generators (called "eggs") distributed throughout the world that basically flip a coin 200 times a second. Statistically, the probability works out to 50/50, but sometimes, these eggs have shown that large scale world events, both positive and negative, have influenced the numbers. The scientists conducting the study hypothesize that this can prove that we are all connected to a larger global consciousness, that attention influences reality, or that future events can be predicted.
Here's an NBC News video that explains it in video:
Plus, it's very meditative to listen to the heartbeat of the eggs in the Realtime Display.
