To keep up the concentration when you're been behind your monitor for hours doing PP? Lately I've been listening to Veneer by Jose Gonzalez. Over and over and.. mike btw you can catch a song of his here and look at LED graffiti at the same time (pretty Cool!) http://graffitiresearchlab.com/?page_id=6 mike
Google what PP is to find it means "Peak to Peak" or "propria persona" and then post about it even though I know it's wrong.
