The work contains a fluid simulation. I put random forces into the simulation and let it run 500 steps to create a flow field and then use it to generate the visuals. I choose fluid simulation instead of curl noise or any other noise function because I believe the fluid simulation could generate a movement that's more dynamic and organic. The result is a combination of big and small vortices. This piece requires WebGL2 to run, please check and make sure this runs on your device in advance. Also you can press the spacebar to toggle the camera control.
