Subo a par da noite

a firme transparência das montanhas,

espreito o silêncio, sondo as estrelas,

persigo cometas, desafio constelações…

 

Artur Goulart, “Em louvor da poesia”, 1999

Adjust the brightness and contrast of your monitor so that you can see each step separately. Pay more attention to the black steps here. The darkest step should be as dark as you can make it while still being able to distinguish it from the next lighter step.
