THE LAB STORY / JACK K.

Before the systems,
there were the patterns.

Early on in applied AI, I built brain-training games for attention, pattern recognition, and recall through play.

That same curiosity lives here: small, abstract challenges about seeing clearly, choosing carefully and keeping a sequence straight. Simulated play, not clinical training.
