So I just read about the Blender logo history when I found information about a demo CD that was handed to visitors on Siggraph. And after searching around the internet, I finally found it.
The CD image contains many different files like the old Blender webpages, some blender files that were unavailable on blender.org, and some blend files.
There are a lot of blend files. Some of them are just simples scenes while others had animations or just a demo. And based on the folder they were put on, those files were made on Blender 1.02 and 1.6.
I put a download link in case that some of you might want to check those files. I also render some of those files that had animation in them.
