Neuro Powder Lab

A falling-sand sandbox that turns into a neural circuit. Sand, water and oil behave the way a powder game leads you to expect; neurons, synapses and wiring run a spiking model rather than a decorative animation.

Draw a circuit cell by cell, drive it, and watch the synapses change weight. The lab uses the same measured firing-regime metrics exposed in BrainSNN research.

Any grid can be shared as a link. The circuit travels inside the URL, so there is no server copy of the grid.
