Couldn't find the files on my PCs, meaning they must be on another one that's in the shed now. I'll try and dig it out over the weekend.
I did find the site at archive.org, though it's incomplete (missing some graphics).
I popped the files from Archive.org back on my site though, so there is at least something now at
http://www.hansen.net.nz/lswtutorial/
The URLs reference the archived version. I'm not spending time fixing when I'm hoping to recover my original files in the next 2 days.
A lot of it is obsolete now unfortunately - the whole thing with installing perl scripts and downloading 2 perl utilities to rip and insert textures is no longer necessary. A better all-in-one utility was made, but that's on the archived PC too.
So feel free to take a look through the tutorial, but I advise against starting any skinning until I find the rest of the images and the new texture extract/insert program. This makes the process way simpler and faster.
