CURVES FROM STRAIGHT LINES

     Here's another optical illusion that can be lots of fun.
Let's make some curves from straight lines.  Yes...that's
right...curves from straight lines.  If that doesn't make sense,
type this procedure and then use 50 for :D and 10 for :A.

     TO FAN :D :A
     IF :D < 0 [STOP]
     FD :D BK :D - 5 LT :A
     FAN :D - 3 :A
     END

Get the idea!  Now play with :D and :A, using different numbers.
What would happen if you made :A bigger?  Smaller?  If it changed
each time the procedure was run...like this.

     TO FAN  :D :A
     IF :D < 0 [STOP]
     FD :D BK :D - 5 LT :A
     FAN :D - 3 :A + 1
     END

What differences do you see?  What would happen if you changed :A
+ 1 to :A - 1?

     So far, the fan has folded out to the left.  Let's label
that procedure FAN.LT.  Do you have to type the whole procedure
in again?  No, that's what LadyBug's editor is for.  Just type
ED "FAN to get to the editor.  Change FAN to FAN.LT in the title
and in the next to last line.  When you press F9 to get out of
the editor, you'll have two procedures...FAN and FAN.LT.

     TO FAN.LT  :D :A
     IF :D < 0 [STOP]
     FD :D BK :D - 5 LT :A
     FAN.LT :D - 3 :A
     END

Now let's change the procedure to go to the right.  Do this in
the editor to save yourself some time.  Change FAN.LT to FAN.RT
in the title and the next to last line.  Then you'll have three
…
