I think Angel is fast becoming one of VPL's biggest fans. After discussing some ideas with him about simple Map-Reduce scenarios for his agent toolkit and a grid system that I'm building, he went ahead and did it. Check out his distributed Mandelbrot fractal generator. Gorgeous results. A bit over-engineered as a fractal calculator, but that wasn't the point really!
