I don’t know if this is the right place to post this, but I just found this site with the most reference material for this subject I have ever seen.

It has everything you could possibly need. From accurate diagrams and photos. To videos and the math behind a horses movement.
Wow. If only you could find something that good for human kinematics… I’ll post the best I could find in a bit.
Who cares about hue-mons!
Thanks for the link!
Great stuff CatBoy.
Oh yeah the horse rigi 
I started to rotoscope the Geri video just to see the horse moving … haven’t finished. Have you done any animation with your rig?

Not really, I have been working as part of a movie project lately. Mostly modeling and rigging, but also some texturing.
Feel free to animate the horse all you want. Just do a good job, because now you don’t have an excuse with all this reference material:ba:. Just kidding;). They even cover gait changes, and lead changes.
