Flash Mobbing

I am really into the idea of Flash Mobbing.
Large scale harmless randomness in public places. The most appealing thing about it is, is that it makes people happy. People love to do it, people love to witness it. Because it usually only lasts 5minutes, its minimal disruption, maximum entertainment!
The power of the internet taken out onto the streets! Locative media at its purest!
I have just found this really eery but cool flash mob video of 50 people in a supermarket in Manchester this March - Check it
Also, mobile clubbing. Its Ace. Check this video
There is a flash mob water fight going on in front of City hall in Cardiff soon. There is a facebook group organising it. I'm going for a look for sure.... Not up for the wetness though! (kill joy).
Right back to work!
(this was legitimate research honest!)
