I find these designs by Mitsuo Katsui extremely intriguing. Of course I don't expect myself to be able to replicate the many techniques precisely, especially the masterful choice of colors. It's the ability to blend three-dimensionally (as if a shape is spinning across an axis) that I am particularly interest in yet have no idea how to do.
Just wondering if anyone knows how to achieve this effect using Photoshop and/or Illustrator. I am relatively new to both Photoshop and Illustrator so any help is appreciated!
