ldesc: "Spiro is the creation of Raph Levien. It simplifies the drawing
of beautiful curves.

Using bézier splines an artist can easily draw curves with the same
slope on either side of an on-curve point. Spiros, on the other hand,
are based on clothoid splines which make it easy to maintain constant
curvature as well as constant slope. Such curves will simply look nicer."
