Thought Experiment: Drawing a Pond Simulation

Any thoughts on the differences of using ets verses an Agent for this? Just curious.

One problem I’ve seen some, using similar approaches to this, is the need to copy the current state into a rending process. A 64 by 128 pond is over 8,000 pads. Depending on the data structure, this memory copy can take time, enough to slow the rendering refresh rates down.
