+# Particle life And FLIP Fluid simulation, with node graph
 This is a combination of a [FLIP fluid solver](https://youtu.be/XmzBREkK8kY), and a [Particle Life](https://youtu.be/p4YirERTVF0) simulation. On each page refresh, fresh rules are chosen for the particle life simulation. **This simulation is interactive, drag the particles around!**

+### Node graph
+The node graph portion can be considered to be a type of self-modifying code; changes to the node graph re-compile a portion of the webassembly code and use it to accelerate the simulation.

 ### Test locally
 Make sure you are using the latest version of stable rust by running `rustup update`.
