Visualization for collatz sequences based on Langton's ant.
Additionally to what's the Collatz function($f(n) = n/2$ if $n$ even, else $f(n) = 3n + 1$) if $n$ even, the ant turns 90º clockwise, else the ant turns 90º counter-clockwise. On both accounts, the state of the cell is flipped and the ant moves forward one unit. This is repeated until $n = 1$.
Example of consecutive trajectories in a single gif (from $n = 10^{30}$ to $n = 10^{30} + 20$).
Keeping count at each coordinate (not flipping state), for corresponding trajectories.
