Hi Christian,

Thanks for the response.

> yes it works, great object! Is the shape your own design?

No and yes. The basic idea of the shape is not new [1] and was apparently
already known in 1969 [2]. However, I did model it from scratch and I have not
seen this shape broken into cubes before. The latter does make it more difficult
to model but I am hoping it will also help to re-enforce the illusion.

That will help, but even then, the illusion won't be perfect. There will still
be differences in shading due to the curvature. Nevertheless, I am hoping that
these second order clues will be masked by the overall outline of the shape and
the bigger shade differences caused by the main face orientations.

Cheers,
Erwin
