I have found it helpful to think through my pond computer research using AI assited codeing. In this patch, I created a simulated pond computer. An 8×8 hypothetical sensor grid is imposed over a 2D simulation of daphnia-like particles swimming around. The daphnia are attracted to light. The 8×8 grid represents LDRs and LEDs (though it could use camera tracking in the long run). Each cell adjusts its LED brightness to keep local daphnia density near a target level (trying to simulate a Stafford Beer-style homeostasis). This work in progress is far from perfect, but it has been helpful in my thinking process so far. INSTRUCTIONS: First click on the patch and try the vairous keys to change settings. You can view
