I had just finished taking some photos at a local blues jam last Friday when I passed a community center and spotted something unusual. There was a wedding reception going on and they had hired a graphic artist to project these really cool light patterns on the front of the building. There were multiple projectors and the patterns were slowly rotating in different directions.... I shot at a relatively high ISO (1250) and a shutter speed as slow as I could and still freeze the shot..... My photos don't really give the display full justice......
