Does this shape game exist as Foss?

I want to install a local version of this game in the link and preferably open source. I searched "shape game" and couldn't find anything.

Use case: before operating heavy machinery, I want to "pass" this game at 8 seconds

You could easily make this yourself with a JS canvas.
- It's already made in JS (but without a canvas).
  
  So, OP: I guess it's already Free and it's already Open Source. Just save the HTML page somewhere.
