Good illustration of skew lines. As described in the article, this depiction illustrates the formation of hyperboloids via the revolution of skew lines. I think a good rule of thumb for math related FPs is "being eye-catching to the point where users will want to read its accompanying article", as suggested on top of this page. This is a good example of it.

Support Should it be noted that there are 3 sets of skew lines (the different colours)? cmɢʟee⎆τaʟκ 01:48, 16 February 2021 (UTC)[reply]
There's also a fourth color of line, the white one in the center, part of the fibration of the space but not belonging to any of the hyperboloids. —David Eppstein (talk) 03:08, 16 February 2021 (UTC)[reply]
