Tunnel — diving through a geometric wormhole

Tunnel is an endless dive through a chrome wormhole. Concentric polygons emerge from the center and zoom out toward the edges, hue shifting as they pass. Move the cursor and the entire wormhole bends — left, right, up, down — like a flight through a hyperspace corridor.

How to play

Move the cursor anywhere; the tunnel bends toward that direction. Adjust the number of sides per ring (3 = triangle tunnel, 20 = nearly circular) and the dive speed with the sliders.

Why it's satisfying

There's a reason 1990s screensavers loved tunnels. The visual loop tricks the brain into thinking it's accelerating into space without actually going anywhere. Tunnel is that effect, plus the gentle steering you couldn't have on After Dark.
