I was playing around with transitioning from one line to the other and was coming up with very annoyingly geometric drawings when I mistyped in the coordinates of a line and spun it around the page.  When it came up on the screen I though, "Whoa!  Where did that come from?"  It's nice how it flows from one transition to the other across the page with many pathways your eye can take.

Take a look at these drawings in high resolution, the lines are truly mesh-like and it really worked out the lines all seem to converge on the same point but in still leads you around the page.
