To start, click "record" or "playback". If you click playback, that is all you have to do. If you click record, you have to draw a new drawing. Change the color with the left and right arrow keys, and change the shade with the up and down arrow keys. Increase the size with M and decrease the size with the space bar. Click to draw. A sample of what your paintbrush looks like will appear in the lower-left corner of the screen. When you are done, click the stop button.
This project is a simple drawing recorder. It allows you to either play back or record a new sketch. You can remix this project with your own list data to show your own drawing in the making. I used the same idea as jtxt, a user who also made a project like this, but I did not use any of their scripts.
