Found this on The Internet Archive the other day.

https://archive.org/details/1078-weird-textures

There it's downloadable as a CD-sized ISO file, but the actual textures are only ~55MB (and are echoed in different formats: JPG, GIF, TGA, IFF, PIC). So I've uploaded the JPG versions of them somewhere hopefully a bit more handy. You should get a little preview of each image, and be able to download them all in a batch or one-by-one.
