I just discovered SprialSilveter -- he is an amazing machinima artist. This video, The Eleventh Hour, is wonderfully made, with high artistic values, including great music, graphics, filming, and plot. It combines real life art and a Second Life visual space to convey a message about "coming your own time lord" as he describes it. Make sure to see it. I am looking forward to viewing his other machinima.
