These are the sample plots I did on the graph paper. At the top is the Hershey fonts with a purple pen that didn't show up well on the green. Below is snail, two portraits, a US map and a Hubble Space Telescope guide star plot. There are also partial plots where things went wrong. One of the tapes I created had a read error. I also didn't always position the next plot properly to prevent overlap so had to abort it and try again.
