Copies in depth: a ring tunnel

Offset Z pushes each copy farther from the camera, so a row of copies becomes a tunnel.

Try this

  1. Press play on the first artboard: the camera flies through fourteen copies of one ring.
  2. Open Modifiers for the rings and click Variation. Offset Z sets how far back each copy sits.
  3. On the second artboard, drag Eye X in Camera. The left globe has depth; the right is flat.
