    Pretty sure the blobs[0] that got left in the code was a mistake.

    Nice video, very helpful. I made metaballs visualization in JavaScript and while it does look nice, it runs very slow if you increase drawing area and number of blobs. I think that it slows down because it has to loop through every pixel and perform calculations per every pixel. Do you have any tips on how to optimize this so that it runs smooth on full screen with relatively high number of metaballs?

    Thanks for your video. When I tried to run this on Android Device, it became too slow(1 frame / 2 sec). but it runs very well on PC or laptop.. Do you know why?

    Oh man, I love all the Coding Train videos I've watched lately, but this one speaks to me 😀
    I remember coding metaball "screensavers" many years ago in QBASIC, and I remember the incredibly old and slow laptop I first tried in on. It had a 16 grey level LCD screen, and rendered a frame every few minutes or so 😛 Several months later and I had a faster colour laptop that could run it properly. Still slow, but fast enough to appreciate it.
    This video brings it all back!

    I tried to do it in p5, but it seems that Javascript isn't fast enough to do this, is it? Did you try it?
