So, for example, the walls in the Alhambra -- I can take all of these tiles, and fix them at the yellow place, rotate them by 90 degrees, put them all back down again and they fit perfectly down there.
Tako, primjerice, zidovi Alhambre -- Mogu uzeti sve te pločice i pričvrstiti ih na žutom dijelu, zarotirati ih za 90 stupnjeva, spustiti ih natrag i savršeno odgovaraju.
