   Concord — console de transmissão

   Direção: equipamento de broadcast. Superfícies quase pretas, fios de cabelo
   em vez de bordas gordas, rótulos em versalete monoespaçado, e uma única cor
   quente que só aparece quando algo está de fato acontecendo. A imagem é o
   conteúdo; tudo em volta é leitura de estado.

   Nada de blur em área grande nem animação contínua sobre o vídeo — durante a
   codificação em alta resolução cada ciclo de GPU faz falta.
