Neon Futuristic Staircase Retrofuturism QR Code for Posters

About this design

A neon-lit staircase climbs between dark skyscraper facades toward a ringed central tower under a cyan sky. The glowing square panels on the building walls on either side act as the finder squares, framed in coral and pale blue light. The checkered steps carry the dark and light modules, with glowing strips on the treads marking the lower rows. Strong contrast between near-black stone and pale step blocks keeps the pattern readable, while the glass handrails and background city lights add detail without crowding it.
