Three frame geometries
Circles, squares, and cut hexagons each preserve a hollow center and clear perspective.
Spatial & perspective
Aim repeated signal frames toward a movable vanishing point and build depth without canvas or WebGL.
Depth from a small set of frames
Use the tunnel for hero backdrops, technical identity, transition plates, and ambient spatial graphics.
Circles, squares, and cut hexagons each preserve a hollow center and clear perspective.
The densest scene remains a small predictable DOM tree.
Shift the center and rotate the entire field without clipping the preview.
Three-step workflow
Start from a restrained tunnel preset.
Set center, depth, rotation, glow, and pace.
Use it as a full page or a contained background.
No. It uses a bounded set of CSS elements.
Five to thirteen frames.
Yes. The rings remain visible at their composed scales.
Yes. Both horizontal and vertical centers are adjustable.
