I thought I had this information somewhere, but I can't find it. The 'funny' images that accompany SuSE Linux (in 5.2 it was blue, in 5.3 green), can they be downloaded from somewhere?

It's one of our CD covers, I think the on of the 5.0. It's some kind of Enriques surface, but please don't ask me about details, the formula to compute this image it pretty complicated...
But perhaps you could tell me what an Enriques surface is?
It is a special family of algebraic surfaces studied by Federigo Enriques. A simple algebraic surface for example are all points that satisfy the equation x²+y²+z²-1=0, which is a sphere with radius 1 and center at origin. Enriques surfaces are something "similar", but the formula is somewhat more complex ;-) In fact, you cannot see an Enriques surface itself, but only some model of it. You can find details in the preface of our handbook if you are interested. It is nontrivial to compute these surfaces. The program that computes the surfaces is on the CD. It's called "surf".

There are very beautiful pictures on this site (go to the "parameter map"). Also, the animation is worth watching. PPS: Want some challenge? Find the formula that gives you a torus ;-) -- To get out of this list, please send email to majordomo@suse.com with this text in its body: unsubscribe suse-linux-e </PRE> </BLOCKQUOTE> -- END included message</EM></P>
