The purple Redux trefoil — three arrows chasing each other in a closed loop. A logo that actually diagrams what the library does, which is rarer than it should be.
Printed and shipped by the marketplace. Prices and delivery vary by region.
The green Flux infinity, drawn as one unbroken line. Flux lost to Redux years ago, which makes this closer to a historical marker than a badge of current allegiance.
The React atom above fn(d) = V — the whole framework compressed into four characters. A function of data returns a view; everything else is implementation detail.
The wartime poster format with the React atom where the crown belongs. The pun is obvious and the design knows it, which is why it commits fully rather than hedging.
MobX's bracketed M on a burnt-orange tile — ]V[ if you read it as ASCII, which is how it was drawn. Observable state for people who found Redux exhausting.
