I think may be interested projecting several p5.js sketches sequentially. If you want to see the submissions of your students with them as a presentation. I think it is interesting for schools.
I created a git repo trying to do it serverless: https://github.com/isaacmuro/p5EasyScreen
And here is the result: https://isaacmg.gitlab.io/sketchs/p5EasyScreen/index.html
Now, only accepts sketches with one js file. Maybe I created something that it exists yet. I don’t know.
