When a star brightness changes suddenly the scattered light from the surrounding cloud does not reach us all at the same time. It is delayed based on the total distance traveled and the speed of light. The result is called a light echo. To better understand how a light echo works I created a simulation of one.
One can create spiraling motions for particles using expressions. This method propagates a local up vector for the curl so that the twist direction does not go through pole flipping as the particle changes direction.
I've modified the roman candle scene in my previous post to use lights positioned at particle locations for illumination, along with further refinements.
One can use nParticles to create a jiggling Jello substance that can be sliced using an nConstraint with breakable bonds. The workflow is relatively quick and easy.
Emergence is a fascinating phenomenon where complexity can emerge through iteration of simple rules or processes. One of the most dramatic illustrations of emergence is the Mandelbrot set where seemingly endless structure and detail arise when iterating on a very simple equation (zn+1 = zn2 + c). I had a little fun and implemented a Mandelbrot texture totally inside a MEL expression. **WARNING: LOTS of hires images ahead...
