01
Gestalt
How perception groups what it sees. The cognitive shortcuts that turn marks on a screen into meaning — proximity, similarity, closure, figure-ground and the rest.
02
Typography
How type carries meaning, hierarchy and rhythm. Swiss and Bauhaus discipline applied to the web — measure, scale, leading and the baseline grid that holds it all together.
03
Motion
How change communicates over time. Purposeful animation — easing, timing, choreography and continuity — descended from Disney's twelve principles and adapted for the interface.
