The Solar System in GLSL

Each planet teaches one technique. You trace an exact sphere for the Sun, light Mercury from the pointer, spin Venus's clouds by latitude, put the sun on Earth's sea, give Mars relief, Saturn its rings and Neptune its air, then set them all moving on Kepler's clocks.

1. The SunAn exact sphere, no marching. Brighter at the center than at the edge.
2. MercuryGrey rock, no air. You move the sun.
3. VenusSulfuric acid clouds. They lap the planet in four days; the planet takes 243.
4. EarthWater that mirrors the sun. One point of light, in exactly the right place.
5. MarsIron oxide and a 4,000 km canyon. The light finds every slope.
6. JupiterBands that run against each other. And a storm wider than Earth.
7. SaturnIce rings ten metres thick. And the planet's shadow across them.
8. UranusIt rolls on its side. The methane keeps the red.
9. NeptuneThe fastest wind in the solar system. And an edge of blue air.
10. Your solar systemOne Sun, eight planets, one moon. Kepler keeps the time.
