Yes I do , I should have mentioned that those images
together with Tom Longtin's first image on this page:
http://www.sover.net/%7Etlongtin/sub_page_3.htm
and M. Trott's little animation at this page:
http://mathworld.wolfram.com/TrefoilKnot.html
inspired me to make this image.

The mesh in this shape was only subdivided once, because my
PC does not have enough memory to handle a second subdivision.
That's why the corners of the holes suffer like you describe.
I wasn't sure if other would notice that.
But now I know, so maybe I should buy some more memory...
Thank you for commenting.
