I am exploring to learn more about Vector Graphics and nested coordinate 

I know almost nothing about Bézier curves, but Juan made this cute 
Sample02Bezier example and I got interested.

There is a great write-up and animations at
but you don't really need to know that much to play around with them

My view of play was to add end-point and control-point handles to the 
HaloMorph for new classes BezierQuadraticMorph and BezierCubicMorph, as 
well as adding MetaProperties to their menus.

To use control points requires translating between three coordinate 
systems: that of the curve itself, that of the HaloMorph, and 
World/Screen coordinates.

Still very much a work in progress, but I think good for a 15 minute 
news item.
