Some of us had to do it by hand in the olden days of 2004 (http://kimberlychapman.com/crafts/ceramics.html#ceramickleinbottles). I want one of these printers so bad that I'm twitching.

I'll post photos of the actual cup soon. cunicode hi, thanks for the comments.

Anybody can point to such a list with pics ?

Also, because this time, my complaint _is_ somewhat pedantic*. You've correctly described the 3-dimensional solid Klein bottle, but not the Klein bottle. The Klein bottle is the boundary. (Like how the circle is the boundary of the disc, or the sphere the boundary of a ball.) Both the Klein bottle and the Mobius band are two dimensional. *: Last time was about as pedantic as correcting someone who calls all animals "dogs".
