A Multi-threaded Go Raytracer

Above is the output of the raytracer. Below is a diagnostic mode showing which goroutines raytraced which section of the screen. Each goroutine has its own color to outline the pixels it traces: I wrote a simple multi-threaded ray tracer in Google's new "go" language. It's an adaptation of Flying Frog Consultancy's Raytracer. It runs single-threaded about 1/2 the speed of a comparable C++ version.
