The Digital Library of Babel (<a href="https:&#x2F;&#x2F;libraryofbabel.info&#x2F;" rel="nofollow">https:&#x2F;&#x2F;libraryofbabel.info&#x2F;</a>) was posted here a while ago, which is a tangible way to search through this space.  The library comes from a book by Jorge Luis Borges, which has all possible books, meaningful and not.  The people in the book are searching for books with meaning, but the chance of finding one is really small.  The digital library lets you do the search electronically.  Kind of fun to play around with.
