---*** Turbowarp recommended !!! ***--- ***[ https://turbowarp.org/1247898887/ ]*** While I was drawing Dragon curve, I found some similarity with the calculation of Collatz conjecture. Click on the [>] button to switch graph functions. I replaced some of the program to draw Dragon curve (specifically the non-recursive one) with Collatz conjecture calculator. actually the graph looks just like a torn piece of felt. not so beautiful :(
