For my project I looked at themes of irreversibleness as well as revolution/insurrection vs art. With this, I built a website where the only interaction is scrolling. There is an icon of a blade that scrolls with you and getting to the bottom of the page there are restraining pieces with information about another person also on the website (id on the server, IP address, start time of session, and identifying information about their computer/browser). Scrolling through this causes the blade to chop this information in half, and kick that person off the server, preventing them from ever visiting the website from their IP address again.
Here are screenshots of it in action:
