[tstzdlrm] You caught a Riemann zeta zero!

Create a game in the style of Pokemon Go based on "catching", or encountering, zeroes of the Riemann Zeta function in the critical strip.  Maybe you could become the first to catch a mythical double-zero off the critical line, a monster conjectured not to exist.

Different Dirichlet L-functions (Generalized Riemann Hypothesis), different segments of the critical strip, depending on time, location, user.

Imaginary axis proportional to time, scaled by T log T, probably inverting with the Lambert W function.
