More a case of a very low performance chip. I've seen this Cyrix out
performed by a Pentium 166 with 16M of memory. With only Exporer, Systray
and Megapov, the final 90 frames took 9.5 hours. Mind you, it was shooting
photons for over an hour of that time. Plus the ring itself is composed of
840 blobbed spheres - 360 for the ring, 480 for the pattern. The setting is
made of blobbed cylinders. The gem is a plain ruby sphere. Blobs always take
ages, anyway (at least for me)
