Intro-style Fade-in/out Star by Mihailo Despotovic, March 1996

A little DOS graphics demo for the 640×480 VGA screen. First the 16 colors of the palette, each with a sample of text; then, at every key press, a star flashes at a random spot: its rays grow out in white, light gray and dark gray, it holds for a moment, and it shrinks away. Esc ends it. Click the screen or use the buttons for the keys.

A new star by itself, without waiting for a key Speed

The star's settings, from the top of zvezda() (“star”)

On the palette screen, “Primer teksta” means “Sample text”; color 00 is black, so its line is written but can't be seen. The star's pixels are the same as the original's: the original zvezda() was run in C, recording the screen at every pause, and every screen matched. The star also switched on the PC speaker at 8000 Hz, for duz_zvuka (“sound length”) of 0 ms, so it is silent, then as now. The text uses an 8×8 font in the style of the BGI's.
