This is a good introduction to what is actually going on here: <a href="http://developer.download.nvidia.com/books/HTML/gpugems/gpugems_ch38.html" rel="nofollow">http://developer.download.nvidia.com/books/HTML/gpugems/gpug...</a>
Quite useful for generating wallpapers - I made mine using it: <a href="https://imgur.com/5VEg1YC" rel="nofollow">https://imgur.com/5VEg1YC</a>
There is an incredible short version of this fluid simulation effect (light and movement) here: <a href="https://www.dwitter.net/d/18112" rel="nofollow">https://www.dwitter.net/d/18112</a>
(just 140 characters of javascript code)
It's interesting to note that the original implementation for this was in Haxe, 6 years ago! <a href="https://news.ycombinator.com/item?id=8325700" rel="nofollow">https://news.ycombinator.com/item?id=8325700</a>
My kids play with this casually now and then (both <4yrs). My 3yo practice reading the instructions which is a intuitive way for us to explore letters/text (mainly "time" and "pixelate" but in Swedish). They love stopping time, enabling pixelate and draw their names. Really love the android app, I even unlocked all the settings :)
Physics simulators like this is something I find really fun to play with, but there’s one thing I’ve been searching for but can’t find any: fluid and erosion simulation.<p>I’ve been playing Cities: Skylines since it came out and I love the fluid simulation in the rivers and mountains and dams, but I would love to see the course of the river change over the years. I’d love to see the rivers carving paths out of the mountains, and have floods/tsunamis change the shape of the coast.<p>I doubt they’re going to add that to Cities: Skylines any time soon, but does anyone know of any toy/game like that? Interactive fluid and erosion simulators?
That reminded me of plasma pong:

Is it only a few tweaks and controls short of being a handy basic 2D fluid-dynamics simulator? I've used this [0] but the UI for barriers is really frustrating.<p>It would be nice if there was something web-based that falls between the extremely basic and things like SimScale<p>[0] <a href="https://physics.weber.edu/schroeder/fluids/" rel="nofollow">https://physics.weber.edu/schroeder/fluids/</a>
