Nicee
u/Ath0r

Thanks! It's the first time I've tried, so probably I missed a lot of tricks to reduce characters... Any feedback or tips are welcome! :D

b is unused so you can remove it :)

Thanks a lot for the suggestions, @13thptr! Indeed, I forgot to remove the unused b and the characters you remove by avoiding the definition of p is also very nice :)

Tinkerbell Map is a chaotic #attractor dynamical system, as described in https://en.wikipedia.org/wiki/Tinkerbell_map

"Origin of the name: the graphical picture shows a similarity to the movement of Tinker Bell over Cinderella Castle, as shown at the beginning of Disney films."

You can replace Xp with p
