This works by controlling redstone lamps in 2x2 cells directly behind stairs that will block the light but still get lit up.
Pros:
- Cheap.
- Works in 1.2.
- High contrast.
- Cool patterns.
- Doesn't look as good as the invisible stairs displays.
- Requires complete darkness at the stairs.
- Slower.
- Slightly obstructs the cells with darkness.
