Platforms for quantum computation create an opportunity to explore parts of Hilbert space of large systems that are normally hard to reach. They also create the opportunity to do so in an interactive fashion. A recent experiment on Google's platform moves us partway towards this vision of a quantum interactive dynamics. I will describe what the experiment, which demonstrated eigenstate order in a time crystal, was about and what it accomplished. I will end with some thoughts on where one might go.
