I've always liked screens full of randomly colored pixels. They're interesting to look at and the programs that draw them are fun to watch.
Fill your screen, or a graphical window, with colored pixels.
- Your program must have an even chance of picking all colors (i.e in the range
#FFFFFF), or all colors that can be displayed on your system.
- Your program must continue to display random pixels until manually stopped (it cannot terminate on its own).
- Pixels can be any size, as long as your output has at least 40x40 "pixels".
- Your program must run at such a speed that it can replace every pixel on the screen/window at least once after running for three minutes.
- Your program must choose truly random colors and points to replace, i.e. random with all points/colors equally likely. It cannot just look random. It must use a pRNG or better, and the output cannot be the same every time.
- Your program must have an equal chance of picking all colors each iteration.
- Your program must replace only one pixel at once.
- Your program cannot use the internet nor your filesystem (
Your output could look like this if stopped at a random time:
The shortest answer in each language wins. Have fun!
