Homer Simpson. Mathematics is no stranger to the Simpsons, see simpsonsmath.com, but this may be the first time that Homer has dabbled in statistics. It appears that he has embedded himself into an infinite do loop! The image above is a spoof of a scene from a Simpson's episode in which Homer tackles a difficult mathematical derivation. Click on the image to learn how it was constructed.
Ronald Aylmer Fisher (1890-1962). This is an embedded-image version of a well-known image of Fisher operating a calculating machine. You can find the original at several places on the web, see here for example. Click on the image to learn how it was constructed.
Below is an animated illustration of a nifty feature available in the new version of JMP software---interactive tuning parameter selection for variable selection methods. The top-right panel contains the forward-selection, BIC criterion selection curve for a data set with the Homer Simpson image embedded in the residual plot (n = 8406, p = 99, 4 nonzero). As the tuning parameter moves right to left toward the minimum of BIC curve, the corresponding parameter estimates can be tracked on the coefficent path plots (top-left panel); and the resulting residual plots appear in the lower-left panel. Thanks to JMP developer and die-hard Wolfpack fan, Clay Barker, for preparing the animation. Read more about Clay's JMP interactive model building routines.

The shadow art below by Shigeo Fukuda is made of 848 welded knives,
spoons, and forks (the kind you eat with, not the front forks of a motorcycle). It is titled
Lunch with a Helmet On.
See more examples of shadow art. Thanks to Munir Winkel for bringing this to my attention.
