This version doesn't start flickering if the Z larger than 8, and also looks like a tunnel if the Z is negative Concept of a tunnel effect using size and fisheye by @papipupepappa The original photos were made by Martin Brechtl https://unsplash.com/@majc0 https://unsplash.com/photos/mining-tunnel-S02FHccCSdA Steven Wright https://unsplash.com/@stevenwright The project contains a distorted version of the photos, cut into differently sized circles. The distortion is because the fisheye effect is symmetric to the center, but the camera wasn't at the center of the tunnel. The cut into circles is because this way the end of the tunnel can move independently from the start, so it can align better to the distortion that moving the camera forward would make
