Details

Go to https://fabmax.github.io/kool/kool-js/
On thte left there is the menu. Click on it and select the very first demo "Island"
Let it load

Nightly: https://share.firefox.dev/49IYTxn 12s
Chrome: https://share.firefox.dev/3VtCMVr , https://share.firefox.dev/3VtafQa 6s

Looks like this is using a bunch of generators. The code is minified, so I have no idea what it's doing or which ones are performance-critical, but I see 79 separate generators in the code here.
