Loved this project! Lots of festive fun in seeing what shapes can be made when unfolded. Just noticed that in mobile Firefox the dotted line previewing the cut seems to have a lower update rate than the actual path recorded, meaning the actual shape is much less jagged than the preview.

Thanks @Liftyee! Yeah Firefox seems to lag behind on the site compared to WebKit or Chromium browsers. Hopefully I can optimize it more for Firefox.

Update: Think I have found a way to speed it up for Firefox (and everyone else too!). On holiday with the fam so might take a couple days before I push a fix. I'm optimistic though!

This is really well made - thanks for sharing (and Merry Christmas)! Small thing: I didn't understand the difference between the white and black options at first. For some reason white was pre-selected so I got confused when nothing was cutting out while drawing for the first time. Maybe a label on hover would fix this while still keeping the clean look?

A label on hover would be nice — or even persistent labels to the right of the circles. I also wonder if instead of black, a dashed outline with a transparent center would make more sense, since you're cutting.

Regardless: This is lovely.

FF Update: Gecko based Firefox isn’t as performant as WebKit/Chromium on desktop/mobile devices when it comes to some canvas operations (even on offscreen!). I was able to greatly improve performance on desktop by limiting how much I drew and played with UV coords instead. That unfortunately wasn’t enough for FF on Android. Had to turn off “live” snowflake rendering for android. It does feel snappy on draw you just don’t get the “live” snowflake preview till you close a drawn shape. On FF Android the snappy draw is worth the trade off.
