Trace the sprite on the screen. To see what you drew by itself, click the "hide" button. To see the picture again, press the "show" button. To erase what you drew, click the "erase all" button. If you want a new drawing to trace, click the "new drawing" button.
Project for school. 8/19/2024 update: Since this is my most viewed project, I should probably support it. I fixed a bug where when the pony drawing is hidden, and the "Show" button is clicked, the cat drawing will appear instead. The pony now appears as it should.
