Infoviz artists tend to ruminate about how people play with computers—and, occasionally, about how computers outwit them. In Thinking Machine, Martin Wattenberg, who is the founding manager of IBM's Visual Communication Lab, invites the public to play chess against an artificial intelligence program. (The piece is a collaboration with artist Marek Walczak.) As the game progresses, the program contemplates thousands of possible moves, which are overlaid on the board as orange and green arcs—orange for the computer's moves, green for yours. With each turn, the options seem to bloom across the grid with mind-bending speed; the machine's overwhelming thoroughness reads as one burst of inspiration after another, as if the spaces between pieces were synaptic. It's like tapping into the Matrix, with a nod to Gary Kasparov, who was bested by an IBM computer.
