This is a 4D-Walker. It has eight legs and using them to walk.
Moving direction is fixed now.
When direction has a few sloped against 3D-ppace,
we recognize easier the walker is crossing 3D-space.
And if the direction sloped large, the Walker quickly fade away somewhere.
You can change 4D depth to drug H-Position bar.
