    Default Some simulated lasers by computer programs as art

    In the computer world there is a scene of people who write software as art to flex their skills and compete.

    It's called the demoscene, and it spawned from the loader intros of cracked software on 8 bit microcomputers. The people that made those intros for the cracking groups came together and wrote entire programs that often pushed computers to their limits and demonstrated that they could do more than usually realized.

    These programs render the graphics and most likely play the music in realtime (think trackers.) It's not a video file, it's just easier to share YouTube videos captured from the output since some of them need high end hardware.

    Here are two more recent demos with lasers in them! Simulated of course, but inspired by laser shows.

    The first is Chiphead by KK/Altair^DMA which runs on the Atari 2600 home game console. Simulated lasers at around 1 minute.

    The second is Ziphead by CNCD & Fairlight. This is the original that Chiphead is inspired by, which runs on a normal PC:

    Oh, and just to blow your mind. Like crazily. There is a subset of the demo competitions where the entire executable has to be a certain size. 64K (as in, 64 kilobytes) is a thing. The entire program has to fit in 64K on disk, it can't call to the internet to get more data or anything. Executable, 64K. That's it. What does one look like? Get your toilet paper ready cause you might make a mess. All 3d objects, music, music player, etc etc has to fit in the executable!!! Obviously fractals and procedural generation is used but 64K... I write emails that are useless longer than that!!!!! Once again, these are videos of the output from the executable. You can get the original executables from hornet.org

    Okay, let's go further. 4K. This post is like 4K!!! 4096 byte programs... This video is from the big 2017 contest where people are revealing their works (Revision 2017) and I just picked one at random they're all impressive.

    Yea. I don't... I get it, but I don't. 4096 bytes.... that program is. Of course it uses 3d routines of the video card, but still.

    i use to have a lot of 64 k demos from the Amiga days running a 14 Mhz motarolla 6800 , this was when hacking was about demonstrating coding skills in a creative way and not about causing damage to peoples hardware

    All hail the Amiga!

    Some of my favorites:

    State of the art (Spaceballs)
    Hypnautic Hamer (Extensors) {gotta wait for the bragging to stop before the demo starts!}
    D.A.N.E. demo (Keffrens) {just for that amazing opening music}
    Cube-o-Matic (Spreadpoint)

    and of course, all the Eric Schwartz cartoons! (Although some of his later ones were very heavily biased towards the "Furry" crowd and feel a little creepy, his earlier works with anthropomorphic aircraft are damned funny even today.)

    PS: Another cool piece of music that *was* set to a demo (but I can't find the demo anywhere) is called "Piano Plinker". It was originally designed to be played on a PAL machine, which meant you only had 50 video interrupts per second, so it played STUPID fast. I preferred to listen to it using NTSC timing (60 video interrupts per second), which slowed the piece down to something more reasonable. Here's the original (fast) version, and a link to one that has been slowed to NTSC speed. That second one sounds almost possible for a human to play.
