Rhino House is an expansive motion library for animators!
Most of the videos are only available to paid subscribers,
but there is always one free video under each section
of each animal in the list.
Each video has frame-by-frame capability,
and allows you to easily step through and pause on frames.
This is a really great resource for drawing and animation reference.
Use it to your advantage!
