Run it in turbo mode, unless you have 20 minutes to sit and wait. I understand how to get rid of screen refresh, but it looks cooler this way. The pen generation is based on some factors set in lists, and changing those numbers allows for a wider range of generations. For example, a formula allows smaller pen size to still cover the whole screen but it will take longer to generate. The background can be modified to have the words you want, though don't make it too small.
That's not my real name, did you think I would put it? Scripting by me. Each time you reset the project, it generates differently. If you'd like to get rid of that and have your own settings, remove the block for random generating and edit around in the list titled "data" and the list "labels" will help tell you what is what. Some color change numbers look really cool, like 5, 10, and 98. Play around with it. Pen size is recommended to be an even number.
