ShowLED demo featuring 2 ShowLED Animation curtains 2m x 2m; 1 with 100 LEDs/m² placed in a grid, one with 64 LEDs/m² randomly placed.
This demo shows that a curtain with LEDs that are randomly placed can produce visuals that are as nice as a curtain with almost the double of LEDs placed in a matrix.
Seems like the human brain fills up the gaps in a random positioned low res LED panel better than in a matrix low res LED panel. Video's with organic shapes also look better on a backdrop with randomly placed LED's.
