      His YouTube tutorial where he creates the beating heart composited on live video as he explains it is a great introduction for beginners and younger people [1]. I've learned so much from his sharing of his techniques and knowledge. Thanks Inigo! [1] this video

    2. @isoprophlexFeb 2020· in “Wolfram Alpha: {y = Re(sqrt(abs(x)(1-abs(x)))), y = Re(-sqrt(1-sqrt(abs(x))))}”

      Highly recommended video by Iquilez, in a similar vein: this video Watching the guy hack away at graphics is super enjoyable

      I was expecting it to be the same algorithm in two different languages, but the Python version is a mathematical description whereas the C version is RLE-compressed. Relatedly, there is this video on how to procedurally generate a 3D heart: this video
