Thank you!

But constructive critical feedback is what I appreciate the most! :)

Sharp turns should in fact indeed cause this behavior as I see it. I don't
think a leg can just skip a turn - it goes up and down even if it doesn't
move much forward.

However, apparently there is another problem with the steps being too small
(glad you noticed it too). I've been looking into that, but it's more
difficult to fix than I thought at first. I'll try to fix it though.

One interesting note: in an updated version of the animation that I've made
but not posted here the spider is hairy and looks more realistic, and I've
got rid of the checker pattern on the ground. The individual frames look
much better, but for some reason that I haven't figured out yet, the
animation looks like stop-motion, like monsters in old movies. That's not
what I'm aiming for so I'm trying to figure out what causes it. It might be
some changes I've done to the walk cycle - or some bugs in my code...

The one on your webpage? To be honest it looks perfect IMHO - I'm not sure I can
spot the monster-movie problem, it looks very fluid. The only fault, if any, is
behavorial. Could you try varying the pace every now and then? He could even
stop to check something out on the ground...

Hit it with a shoe!  Extremely nice animating Rune.  Has a life-like
appearance, the way it traverses that surface it's crawling over.  Each leg
seems to be sensing for ground to cling to.

Oh thanks! :)

But in the meantime I've made a newer and much better version which can be
found here:
http://rsj.mobilixnet.dk/3d/anims/anims.html

I posted a note about it in povray.binaries.images, but you may have missed
it.

Thank you! Glad you like it. :)

I've made a newer version that is more realistic which can be found here:

I posted a note about it in povray.binaries.images, but you may have missed

Everybody has lauded your animation, but I need to say it too: it's amazing!

Congratulations,

No, not the one on my webpage. An earlier version that I've not published
anywhere. Later I managed to fix the problem, and that's why the one on my
webpage looks fine.

He *is* varying the pace (he moves quicker in the start and end of the
animation). But stopping completely is still a problem, as I haven't worked
out support for that yet.

Thank you!

Indeed the positive reactions have been overwhelming! That, needless to say,
is a great motivation to continue. :)

My mistake - btw the anim *almost* loops, can that be fixed?*

* as in "does loop" rather than "doesn't even attempt to loop"
