Digital Artist Collaborate

I am not sure where I came across this a few days ago…I think my Google reader revealed it.  I tried to research the background just a bit because I really love this idea.

The painting evolved by four digital artists working simultaneously on the same digital canvas, it was unplanned and free form.  Communication was made possible by text chat and the artists worked from  each others actions. The total elapsed time was 4 hours.

While the video was put on Youtube in August of 2009, I still had a difficult time finding much about it. Who were the artists involved? What software were they using? How did they draw simultaneously while each was in a different location? Was it iscribble.net and the interactive canvases on the draw-chat site?

There are several ways apparent to do this so  what method did they choose? Anyway, I hope you enjoy it as much as I did.
