A wind you can only see where something stands in its way

The solar wind streams across the frame, and the two largest things in the piece are never drawn: the sun is a bearing off-frame, and the planet is the shape the wind bends around — a standing shock, a boundary it cannot cross, and an airglow limb along the bottom that lights only where particles rain onto it. Every hundred seconds the tail loads and lets go and the limb erupts in curtains. Once a cycle a storm arrives as a shock sweeping the frame and presses the shield in; every other cycle it comes as a great storm and the whole limb goes red. A moon crosses with a wake behind it, a comet comes every minute and tears when the storm catches it, a star in the field goes and its light, its rain and the pulsar it leaves reach the wind in turn, and once a cycle the piece pulls back far enough to show the planet whole. You are a third field: move to comb the wind, press to wind it into a vortex, fling to seed a storm, and tap anything you find — the moon, the comet, the derelict, the star that went — because everything here answers. Hold still, and it answers that too.
