About Macro Data Refinement
Sort scary numbers into bins on a Lumon terminal, recreating the work from Severance.
You sign in to Lumon Industries with any name and are put in front of the Macrodata Refinement terminal: a grid of drifting number clusters that you sort into bins, exactly like the job in the show.
The aesthetic is the point - eerie CRT-terminal blue on black, with the Lumon globe logo and a chiptune music player docked at the side.
