Never heard of "dogpile" before. Are you referring to dogpile.com search engine?
A week or so ago I was frantically searching for "hidden bird illusion", and could no longer find the animated gif on wikipedia, and also nothing related to it on DDG nor Google, until about an hour later...
I just tried "hidden bird illusion" and it gave the michaelbach.de page within first page...
Thanks for the recommendation if you guys were referring to dogpile.com it's always good to have a backup search engine...
dogpile was/is a metasearch engine.
Back before google days there was so much unindexed stuff out there each search engine could bring back different results.
Going to this one site and searching would bring back results from all the popular search engines at one time.. querying sites like (altavista, lycos etc.)
