Namely Casey Reas, who co-founded Processing and it's namesake foundation!1 Strikes me hard as I have always known about Processing. I used to watch Carykh talk about his pre-ai ai videos, and how he created Yoyleland in Processing 3. I learned how to code through Daniel Shiffman and his Processing and p5 tutorials, and I literally would not have this website if it was not for that.
