Unfortunately for this project, I was unable to make it work completely with the server in Glitch. For this post, I'm sharing my trials and showing things that did end up working.
Shown above is an example of the convex hull algorithm I implemented in the p5 editor with some mouse interaction. I was interested in creating a generative gem or some kind of abstract shape with the cursors of each client visiting the page, but as these things sometimes go, I could not get it to work in Glitch. I liked the idea of a shape growing and shrinking as a group of people collaborate on its formation, all the while leaving history of each move made with the trail of points each cursor would leave.
