I have been meaning to post some info on the Plateaux Festival in Poland. The entire festival is focused on Audio Visual performances and installations. I performed with Geoff White in the 2008 festival. I was running VDMX on a 15" macbook pro.
Here's the festival website; http://www.plateauxfestival.pl/
Here's a link to short video of our performance; http://brianbixby.com/?p=35
