Default The catenary effect

Except that a circle has a constant radius and a catenary has a constantly
changing radius.


If you can do a parabola that could be close enough. Not the same as a
catenary but a damn sight closer than a circle's arc, and much more likely a
form for a tool specialising in projecting energy to be able to do.
