I was clearing up some harddisk space on my office computer when I found an article I wrote for my organization's quarterly newsletter about four years back. And it is on the subject of - no surprise - kerises!
I thought it was a nice little piece, great for the unintiated. I've edited it a little bit, plonked in more and bigger pictures and uploaded it to my old website (which was still around! I'm amazed!).
Anyway, here it is. Don't flame me for the content, but I'd gladly take comments.
