I use the photos of tunnels and tunnel-like paths from the original project. be careful - it may induce dizziness.
The project uses size and fisheye to make this 3D effect. The effect is as precise as possible near a circle with a given radius, *if the image is a square that shows a tunnel that's a cylinder that's centered at the middle (i solved the math for this case). The conditions aren't actually true, but the effect is still quite good on some of the images. The effect could be made even better by cutting the images to concentric rings, because that could prevent the center going in the other direction.
