Thanks Kim --
... we should probably write up something about what they mean and how they can be used ...

Hi, Randy/Alan -- Randy is indeed using the latest/greatest "Etoy/Squeakland" version. Both "theta" and "headingTheta" appear by default in the geometry category of an object's viewer in this version. -- Kim

Uh, I said "Squeak" backwards 3 times really fast? :) It's possible that my environment may be a bit screwy. Early on I was using some full-blown version of Squeak, but thought that I was currently using the Etoys version. The world -> desktop menu -> help -> "about this system" tells me I'm running Squeakland 3.8.5976 update #371

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?

Hi Randy,
Attached is a quick, if somewhat simple-minded, fix.
Best,

How might one create a script to draw a spiral? I mistakenly thought
that
if I did something like:
Fwd by 5 Turn by <obj> headingTheta + 2 penDown
that I might accomplish it. However, it seems that the headingTheta
is not
dynamically updated in this script, i.e. the heading never changes.
Thanks, Randy
