Looping tunnel video effect

I think this was done simply by animating shape layers to scale down. The scaling has that look of exponential collapse, as opposed to when you move layers further away.

Yes, it can be done in After Effects. Adjust the shape layers and their size, position, and curvature. You have to make sure that the animation transist from the end to the beginning. This can be done by copying and pasting keyframes or by using time-remapping methods.

Give some depth and visual interest, use effects like Radial Blur, Glow, and Stylize to get the desired look. Adjust the effect parameters. This general outline will help you create a continuous looping illusion effect.
