Hello everyone,
I need a little help drawing spokes to a wheel. This is actually
used in a vision test. I have an image here to help illustrate the
madness. I am sure someone like Jim Ault is shaking his head right
now. <http://www.canelasoftware.com/pub/rev/astig.jpg>
I have been using an image, but would like to offer the ability to
adjust the line length and thickness. The new antialiasing feature
will also be handy. Thanks for any input.

Mark,
You may be able to guess what my solution might be; that's right
Turtle Graphics.
on mouseUp
startTurtle
put 12 into tNumSpokes
put 100 into tLengthSpokes
repeat 360/tNumSpokes
forward tLengthSpokes
back tLengthSpokes
left 360/tNumSpokes
end repeat
stopTurtle
end mouseUp
Paste this handler into a button in the stack:
go url "http://home.infostations.net/jhurley/StopTurtles.rev";
Or if you want something like the clock in your graphic;
go url "http://home.infostations.net/jhurley/Build_a_clock.rev";
There are lots of variations possible.
Jim
