/* The Solarian Arcade: four windows onto floating worlds, in deep space under a
   rising sun. Hovering a window pops it out, lights its sides and turns it
   toward the cursor; its island lifts and the layers slide apart for depth.
   The background stays still; the only thing always moving is the islands'
   gentle float, so slow computers cope. */
