A terminal animation that simulates "neurons" on a grid. Each neuron randomly dies or moves in one of four directions on every tick, producing an evolving pattern printed to the terminal.

The terminal fills with a live-updating grid of block characters (██) representing neurons. On each tick every neuron either dies or moves one cell in a random direction, producing a shifting, organic-looking pattern that runs until all neurons have died, then restarts.
