I understand that photons are their own anti-particles.  Are there any 
other elementary particles (either fermions or bosons) that are their own
anti-particles?  Why doesn't the photon have an anti-particle other than 
itself?  How about the hypothetical graviton (I think I have seen 
references to all other anti vector bosons)?
