Huge thanks to my Patreon supporters. My gratitude to them is infinitely recurisve. CORRECTIONS - At 02:32 I said that the complex locations was scaled so the height of the frame equals 2. For the examples on screen, we also made the width 2 by stretching it. But for actual pixel image transofrmations we used a linear scale for everything that made the height 2. - Let me know if you spot anything!
