What makes a tunnel effect convincing?

Consistent perspective convergence and darkening toward the vanishing point. Real depth cues — things getting smaller, dimmer and less contrasty with distance — are what stop it reading as a flat spiral.

Which images suit a tunnel warp?

Ones with a strong central subject and a background that can afford to be distorted. Radial symmetry in the source helps enormously, since the warp is itself radial.
