I remember an article *somewhere* about relativistic effects with an experiment
someone made with - ta-daaa - a modified version of PoV-ray!

So it must exist somewhere out there already...


The experiment showed the classic 3D-teapot zooming past the camera at about the
speed of light, and the PoV-ray version was tweaked to take speed of light into
account.

Much to the surprise of the readers (and possibly the experimentor as well), the
teapot did *not* look "squished" as is often claimed in popular-science articles
about relativity, but rather *rotated*!


Geez, if only I could remember where that article was! c't maybe (a german
computer technology magazine). I'll try to dig that up.
