I'm fairly new to Houdini and this my first post, so hello!

Right now what I really want to create is a Optical Flow like texture. On a website I saw the exact thing I want to achieve but it was done with C4D, now I just want to re-create it with Houdini - I'm sure it can be done.
You can see the thing I'm aiming for here on the second half of the video, on the right side: https://www.cinema4dtutorial.net/?p=4783 [www.cinema4dtutorial.net]

If anyone can help me with it I would be much grateful, I really like how the colours change as the model rotates.

Best wishes and thanks again.

This might be useful.

Thanks a lot, I actually checked that out but didn't help very much. I think what I want to achieve is more about the material.
