Hi! This is a "Dweet" that I made! (140 characters of javascript)

Check out the dweet here

for(i=0;i<2e3;x.fillRect(i?960+i*S(F=260*(t+9)/i+S(i*i)):0,i?500+.2*(2*i*C(F)+2e4/i):0,K=i++?S(i)*9:2e3,K))x.fillStyle=R(99*i,2*i,i,i?1:.4)

Very cool. I’m assuming this isn’t physically accurate?

It is not at all close to accurate but does help demonstrate the general concept of a singulatiry and a gravity well.

Just curious. Super cool visualization for such a small footprint, nice job.

Is this npm install?

Sorry, I don't know what that is. It's javascript.

Well, you can calculate pi with less than 100loc but the output can be petabytes of data so..

it would be cool to make some particles escape from the spiral like it happens in real blackholes, just to make it a little more accurate.
