Wally Wood's incredible "Fully Computerized" illustration

Thom Buchanan of The Pictorial Arts says of this mind-boggling Wally Wood illustration:

This piece by Wally Wood, which I don't think was for EC [the comic book company that published MAD, Weird Science, and Tales from the Crypt], is genius for its organized complexity—seemingly effortless in its execution. Zoom in on the figures and see how fully realized they are! I cannot overuse the word when it comes to EC guys—they were geniuses!
