+This animates a Klein bottle, the 4D analog of a moebius strip.
+
+You can walk on the surface of the bottle or rotate it in 4D or walk
+on it while it rotates in 4D. Inspired by Thomas Banchoff's book
+"Beyond the Third Dimension: Geometry, Computer Graphics, and Higher
+Dimensions", Scientific American Library, 1990.
