My favorite 2D liquid simulator is this IOCCC2012 submission [1]... simply astonishing. That is the source file shown at the beginning of the video... it compiles without warnings, runs a full blown fluid dynamics sim with surface tension and everything, can take itself as its own input... truly a work of art.

Oh, that is cool! I love that the code itself can be used in the sim - reminds me a bit of 'quines' from GEB: http://www.madore.org/~david/computers/quine.html http://www.madore.org/~david/computers/quine.html

  Perhaps there is material for a game sequel titled 'Baba is Goo'

  That one is brilliant - I just realised you can change the light direction. Another classic: http://david.li/fluid/ http://david.li/fluid/

    this is probably the best form of user interaction with simulated fluid I have seen

  This one looks like a shallow water simulation, rather than a fluid simulation in the sense of handling pressure etc. Rendering is gorgeous though!

    I think it’s way off. It looks surface waves propagate without dispersion — tap it and watch the caustics. Real water haves have the packet of waves and the individual peaks and valleys moving at dramatically different speeds.

  I was going to reply this is at least 10 years old and it was already butter smooth the first time I interacted with it (with even older hardware, from when webgl was still a novelty and not widely supported across browsers) And indeed it's at least 11 years old according to this youtube video https://www.youtube.com/watch?v=R0O_9bp3EKQ https://www.youtube.com/watch?v=R0O_9bp3EKQ

  It’s very impressive how well this works on mobile.

Holy hell that's cool. Thanks for sharing.
