Have any extra dimensions been found?

No. That would be cool, but no.

The idea that there are extra dimensions as large as to be detectable in collider experiments is a very exciting prospect, but it's not the main point of extra dimensions. Theories with extra dimensions (almost exclusively superstrings/supergravity) don't require them to be anywhere near this large.
