Low-Resolution Pixel Wall: Dynamic Imaging with Large-Particle LEDs

Design a public media artwork built from deliberately coarse pixels. Show an entire building gable, some twenty metres wide and thirty tall, fitted with a grid of individual LED nodes spaced four hundred millimetres apart — around fifty by seventy pixels in total — mounted on a fine open framework so the wall behind stays visible by day and the array almost disappears. Detail the low resolution as the artistic decision rather than a limitation: the image displayed is abstract and slow, broad fields of colour drifting and bleeding across the grid, with no attempt at photographic detail, so each individual node reads clearly as a separate point of light. Show each node as a soft glowing sphere rather than a hard rectangle, with a visible halo, so the array reads as luminous beads rather than as a screen. Detail the colour as limited and considered — deep blues shifting through violet into a single band of amber crossing the field — with large areas left completely dark so the building's masonry shows between the lit points. Show the surrounding city as dark, the array the brightest thing in view. Detail people in the square below looking up. Set it on an urban square at night. Photorealistic, pixelated, glowing beads on dark brick, low upward three-quarter view.
