In my younger days, I used to play around with software like maya.

The best thing about voxels is what you can do with fluid simulations.

In Maya you could create a cube made up of voxels, each voxel had a fuel, temperature etc variables.

You could start a fire from a single voxel, and watch is spread ! Changing the values could make the fire behave differently.

I wish front-end javascript was that cool :( fire simulation on a computer is so much more fun.
