Ooops. Forgot to specify - there are 200 frames in the animation,
20 per second, so it should complete one loop in 10 seconds. The
little pointer circles around the fake Earth once every 10 seconds,
regular as clockwork on my 2GHz 2Gbyte Thinkpad T30.
I guess I am spoiled by Verizon FIOS. The 4mbytes of animation
downloads faster than it displays on my link. I should try looking
at it someplace with less speedy bandwidth.
Strangely, though, when I present it as part of a wiki page:
http://www.server-sky.com/ap02
... it is 3x slower, maxing out the CPU on my laptop. At the tail
end of a longer wiki page:
http://www.server-sky.com/ToroidalOrbits
... it displays fast. I am still scratching my head on this one.
As a slide show with local content it will of course be faster,
and folks wanting to download the slide show will probably end
up downloading a zip file with all the pages and images. One of
those presentations will have half a dozen animations, and may
run a hundred megabytes or so - it will be a lot less compact
than an openoffice file. But it will be portable, and look nice.
