I know it's a bit gross. I made this on stream and just wanted to share :)

Did it work as you expected ?

Why don't you try to contribute by adding this kind of dance ? Could be challenging but really fun ! (Check out the "Contributing" part README, adding a dance should be easy)

Wow awesome link ! I will try this out for sure :p !

Could you fill up an issue on github with all your specifications ? I think this is worth investigating.

The other answer show exactly the good code lines.

To describe it fast : I keep an history of frequency (size customable) and compare the subscribed frequency range to its relative history max / min value. I get a percentage out of it that i give to the dance function associated to this specific class.

There is library to make easter eggs using konami code. My company did use it along with rythm.js if you want to check it out. https://www.zenika.com

You're right :), Rhythm.js were taken and Rythm is close to the initial french spelling.
