I have recently been scanning the old threads for times that were much more simple and converting where necessary to build source code (where given) on a 64 bit Linux platform.
I came upon the post https://www.dbfinteractive.com/forum/index.php/topic,3101.0.html [PROCEDURAL] glsl_plasma by Dr_D.
In the thread a conclusion to the code not working on many users setups was never sought, so I have made some changes for it to build and run on my Linux 64bit setup.
I didn't want to necropost in the original 17 year old thread so I'll post the updated .ZIP here, if any mods wish to move it to a more relevant location then feel free.
You may ask why am I bothering? I still find all these past little examples to be still great to the hobby programmer and remain a good source of simple examples.
It's a shame how many have been lost due to posting remote links to source, executables and archives rather than attaching to the in forum post method as Shockwave did, most of his examples still remain because of this.
