Day 010 — Dead Channel

"The sky above the port was the colour of television, tuned to a dead channel."
— William Gibson, Neuromancer (1984)

A visualization of the iconic opening line. An industrial skyline photo used as a mask over WebGL shader-based TV static noise, layered with cloud textures and a semi-transparent water reflection.

Tech

• WebGL fullscreen fragment shader for TV static noise
• Adaptive local threshold mask (integral image) to extract the skyline silhouette from a photo
• Two cloud photo textures with UV warping, crossfade morphing and tonal shifting
• Sky gradient (dusk/night atmosphere)
• Semi-transparent water zone with noise bleed-through
• No framework, no external dependencies
