From the log it looks like the desired link was http://www.cupery.net/SH.html, so we've added it above.

It's a great submission. Obscure but curious things that haven't appeared on HN before are some of the scarcest goods here.

Ooooh. I've seen this page before, but it is a great submission. Fascinating article about something I'd never heard of before. Thanks for the link.
