One of the moments that I can think of was when I began the letter A.
My R used only 45 degree angles and I didn't realize, when I drew my
sketch for A that it didn't use those. Instead of redrawing A, I used
trig to figure out what angles I needed. The toughest part was getting
the hole to be in the right spot. That took some trial and error with
the code to make sure the turtle started drawing in the right place,
and went to the right spot after completing the hole.
