LED Party Ball

Here's a unique way to really engage a crowd! Tangible, an interactive design agency, invented this lightweight inflatable orb they're calling the "Zygote." Inside the blow-up ball are LED lights that change colour when people come in contact with it, whether they're hitting it, bouncing it around, or bumping it around to others. Check out the video to see an Italian crowd go wild for the fun spheres in Florence this July.

"You've probably never had the pleasure of smacking around a one-and-a-half-meter sphere that responds to your whacks with multi-colored blinks," wrote Engadget. "Now you and your New Rave posse can really get into the "groove" by violently tossing a gigantic orb of light into the air, and then watch as fellow hedonistic revelers join in the fray."
