Stolen shamelessly from Wikipedia’s “Fourth Dimension” article, where it illustrates a four-dimensional object rotating on one axis. The graphic was orginally uploaded by Jason Hise, who is apparently responsible for a similar graphic of an 8-cell tesseract rotating in two planes.
Five minutes later, I’m still zoned-out looking at the illustration, wishing I could slow it down or step through the process one frame at a time. I think my mind has been blown. Trippy.
Take a look at the one rotating in *two* planes.
