I have a few art projects that utilize PixelPushers for their lighting needs. According to the website:
"We supply a free, portable bridge app that makes PixelPusher's advanced protocol work with Art-Net and E1.31, so you can drive tens of thousands of pixels from a professional lighting console or media server."
Has anyone used these units with Lightjams? It sounds like they would work but I know from experience just because something supports a given protocol doesn't mean that it works exactly the way you expect :)
