Bézier curves are used for drawing curved lines in vector 2D programs,
originating
with Adobe Illustrator back in 1988. They allow computers or computer
using artists
and designers to draw curves that aren't sections of an elliptical arc.

They also extend into 3D drawing as Bézier surfaces or patches, with 16 control
points instead of 4.

The "aesthetic effect" can be simply that, like lines, they can be
scaled to any size
without corners or jaggies. Or that, once you've got some initial
practice in, they
are easy and quick to sketch with. Or that the maths behind Bézier
curves is simple
and elegant without the mind-melting complexity of NURBS, and the computer code
to draw a Bézier is therefore quite straightforward.

In case you haven't worked it out, I like Bézier curves :-)
