Spanish Bank Flash Mob

Flash mobs are instantly a zillion times better when they involve classical music.

Although these two are still my favourites.

Copenhagen Phil

The latest flash mob from Copenhagen Phil is every bit as wonderful as their first. Here are both. I just wish I could have seen one. 

Ripley Rompela Flash(Mob)

This is the second good crowdsourcing idea I've seen in just as many days. Ripley, a Chilean clothing and footwear company, wanted their catalogue to be a little different than all the other catalogues. They set up a outdoor photo studio, and invited all their fans to come and be the photographers which meant photos shared on every social media imaginable. The final results were then uploaded by Ripley, and the photos with the most votes got to be printed in their catalogue, together with the photographer's name. Pretty good idea.
