This is really awesome. Thinking Machine 4 has an online chess game that lets you watch the computer evaluate all of the future moves in real time each time its the computer's turn.
When the machine (Black) is thinking, a network of curves is overlaid on the board. The curves show potential moves--often several turns in the future--considered by the computer. Orange curves are moves by black; green curves are ones by white. The brighter curves are thought by the program to be better for white.I found this posted by Nathan on Simple Complexity.
