 The simulation can run in real-time as it utilizes WebGL for image rendering, resulting in an image that closely resembles a lava lamp. It can be used as a screensaver or wallpaper. However, if you desire a more complex simulation, you can modify the simulation settings (the button is located in the lower-right corner) and increase the particle count or make other parameter changes.
