Pyro FX simulation. Scaled correctly, the letters are about the height of a washing machine and the width of almost 2 washing machines.
This isn't rendered, just captured from the viewport.
Created in Houdini 13. Gamma is at 1 otherwise you would see some funky artifacts.
Fuel and Temperature are emitted from the particles. The floor particles is transferring the temperature to the letters.
Let me know what you think! I'll have a rendered version soon.
