Patterncollider: Generate and explore quasiperiodic tiling patterns (github.com)

The grid and sliding tiles illustration is great, I've never understood it that way before. Thank you!

So cool! Really looking forward to playing around with this.

It was also a great little explainer of how these tilings get made. One question: how do you guarantee/prove that the tiling you get back from the grid is quasiperiodic?

Really cool tool. One detail: the instructions do not say what selecting tiles or lines do, it doesn't seem to do anything besides highlight the item on the other panel, what is that for?
