Neat effect! You do FFT and map the frequency to the radius of the circle?
Also, I have nightmares about getting my junkpile-find dot matrix Epson to print legibly enough to turn in a school report the next morning...
@nina_kali_nina Sounds like a pretty fast one, assuming that printing the ASCII art you just posted above. Mine was more like 1s to print a full line in both directions. 😅
I wasn't paying for supplies back then but I presume ribbon ink wasn't a rip-off, unlike today's inkjets 🙃
