COMMENTS
| Start from any complex number z=x+iy, not solution to zeta(z)=z, iterate the zeta function on z. If zeta_m(z)=zeta(zeta(....(z)..)) m times, has a limit when m grows, then this limit seems to always be the real number C=-0.2959050055752....

EXAMPLE
| Let z=3+5I after 30 iterations : zeta_30(z)=-0.29590556499...-0.00000041029065...*I
