What happens if the balls hit each other, singularity event?

Lazy browser console hack to speed it up without locking the browser completely or rehosting:

  (()=>{for(let l=setInterval(()=>{},0);l;)clearInterval(l--);const c=new MessageChannel;c.port1.onmessage=_=>(draw(),c.port2.postMessage(0));c.port2.postMessage(0)})()

It seems there are a lot of buggy positions which clear themselves given enough time. I managed to make it to 1,000,000 iterations without any permanent lockups (but some lasted a while)

The neat thing about this is that it's self-balancing: if one side grows smaller, the ball bounces more often and increases how quickly it regains territory.

Wasn't there a version of this with the yin and yang symbol posted recently? (Also there's a 2 year old hn post of this same thing)

This was posted a while back. I thought it was beautiful:

Would love if there were some screenshots in the readme! Just my two cents :)
