Yeah, thats the one. Not sure why that search was dead. Maybe it is only stored for a limited time, if at all.

If you read through the thread that Poison linked to, it will tell you which folder to put it. Once it is there, start Gimp and it will be under the Filter>>Render>>Pattern.... The link also explains how to use it

in Gimp 2.8 you put it in : C:\Users\"username"\.gimp-2.8\scripts, where username is the login you are using.

Hope that helps and sorry for that dead link
