The Walking Cube

The Walking Cube is a rig a created in Houdini trying to create a procedural walk cycle. The main attribute keyed here is the distance of travel, and the cube walks along a  curve as its path.
The cube can swing, tilt, have hands, walk downstairs, upstairs, down and up a hill, bounce, turn sideways and all can be changed and keys. Ramps control the feeling of the walk so many kinds of cycles can be created.
In addition controllers are connected for addition keys if needed.
All the movements are mathematically correct with no driven keys or what so ever.
I have tried to create this for some time now using, 1st Maya, then Softimage, and at last Houdini.
If there will be interest in the Houdini file i will upload it.
