David noted in his REVisions : Grid Economics article:-

'But, Felix Mottram, founder of The Decorators <snip> had an idea one night. Maybe it came to him in a dream, or he looked at something and an idea popped into his head, but he began to try and get some of us to get our head around it. And to be honest it made no sense to me initially, I know I had problems visualizing how it would work. I don’t think I “really” got it until such time as Felix worked a group of us through it in Uchinada earlier this year.'

and:-

'And, the first time I got to experience it first hand was in Uchinada Beach where Felix had managed to make his way over to the festival.'

I had started to try and document the process of getting a large Revolution Team event together by copying all the messages in the Revolution Event 2008 thread into one place but it was too painful.

I arrived at the idea of the Grid in 1993 and wrote to Revolution at that time.

Having proposed the Portsmouth/Bristol events it was apparent that all the players would need to be on-side if we were going to attempt the Grid format. Having been at the rained off event at Uchinada in 2004 I had some reason to try and get there again.

Serendipity comes to mind.
