This looks nice and oddly nostalgic. One bit of feedback: each time I toggled the checkbox I expected the checkmark to look slightly different, as if it were being redrawn by hand each time. Adding some "noise" might be a neat feature for a version 2.0.

Adding a noise would result differenet look on every render, I am not sure that's good

It already does that, though.
