Sagitta
Sagitta is a night-sky guide, and its hero is an archer drawing a bow that is a constellation: eight stars joined by light, a real bowstring, and an arrow that forms on it and aims at your cursor. Click anywhere and it flies to the nearest named star, the star pulses, its constellation draws itself out of it from real J2000 coordinates, and a label springs in with its right ascension, declination, magnitude and how high it stands for you right now. A boiling nebula, 2,600 twinkling stars, a light beam and bloom around one matted, hosted plate. Built in HTML and Three.js, one file, no build step.
