+Repeatedly rotates a bitmap by 90 degrees by using logical operations:
+the bitmap is divided into quadrants, and the quadrants are shifted
+clockwise. Then the same thing is done again with progressively
+smaller quadrants, except that all sub-quadrants of a given size are
+rotated in parallel. As you watch it, the image appears to dissolve
+into static and then reconstitute itself, but rotated.

-The ``blitspin'' hack repeatedly rotates a bitmap by 90 degrees by
-using logical operations: the bitmap is divided into quadrants, and
-the quadrants are shifted clockwise. Then the same thing is done
-again with progressively smaller quadrants, except that all
-sub-quadrants of a given size are rotated in parallel. Written by
-Jamie Zawinski based on some cool SmallTalk code seen in in Byte
-Magazine in 1981.

-As you watch it, the image appears to dissolve into static and then
-reconstitute itself, but rotated. You can provide the image to use,
-as an XBM or XPM file, or tell it to grab a screen image and rotate
-that.
