In the Rydbergator you can play with a system of atoms confined to a plane. You can excite them in spatial patterns, and you can see how such patterns evolve with each laser excitation pulse. If you like, you can choose among different physical parameter settings, and see how that influences the dynamics. You can define games and challenges so that you can compete with your friends on who gets the largest number of Rydberg atoms, whose atoms get to dominate a specific domain, or who conquers the atomic flag.
