that form a circle drawn inside another circle be considered parallel?
 Parametrics [12/18/1996]

You're in 3D space at point A, you want to get to point B, and you know
the coordinates to point B from point C (but B is moving). What heading
do you need to set in order to meet point B?

larger than the original, can be passed in one end and out the other?
 Pattern for Lampshade [02/17/2001]
