An Interstellar-style black hole — a glowing disk bent by gravity around a dark shadow — rendered live behind a GPU-cloud landing page.

A retro-futurist sunset in one shader: a striped sun, wireframe mountains and a racing neon grid, finished with scanlines, bloom and VHS wobble.

A giant planet low in the frame, a sun rising over its glowing horizon, satellites on orbit trails and a starfield — all live 3D.

A light-speed tunnel that accelerates as you scroll, with story panels that fly out of the vanishing point and an arrival into pure light.

Click a planet to fly to it: a shader Sun, eight procedural planets with real Earth coastlines, Saturn's rings and NASA fact cards, clearly marked not to scale.

A deep night sky with realistic star brightness and colour slowly turns over a hilltop observatory; hover anywhere to trace a glowing star figure.

A playful 404: a code-drawn astronaut tumbles in front of a giant 404 on a drifting tether, above a planet horizon — and you can catch stars to restore the signal.

Fly over a glowing wireframe terrain while a laser scans the ground, with a live HUD: telemetry, a heading tape, a mini map and tags pinned to real peaks.
