Hallow This project demonstrates Hasse's Algorithm. This says that if you take a number and put in through these rules, it will always fall into a loop of 4, 2, and 1: If the number is odd, multiply it by 3 and add 1. It is' even, decide it by 2. So far, nobody on earth has solved it, but I've created a tool that demonstrates what happens to a number during this. The start num is the number you put in at the start. The highest num is the highest number that has come out of your original number, num is the current number your process is at, and x pos and num is showing you what the num was, when the cat was at your mouse's x position. Finally, once the cat's line turns red, you have entered the 4, 2, 1 loop. Have fun!
