To John and Randy

By the way, headingTheta is part of the vector category in etoys, has a 
different purpose and orientation than "heading", and is not needed for 
making spirals or other LOGO like geometric figures. "headingTheta" (and

the rest of the vector stuff) is usually not visible in a vanilla Etoy 
system. How did you get it to be visible in yours?

Cheers,

Alan
