Here is the start of one sort of approach. It seems ot have some
bugginess though. But perhaps this will get you going:
With[{plot =
ContourPlot[Arg[Gamma[x + I*y]] == 0, {x, -10, 10}, {y, -10, 10},
PlotPoints -> 20]},
Dynamic@Tooltip[
plot,
(With[{z = Complex @@ MousePosition["Graphics"]},
{z, Gamma[z]}])
]
]
I suspect that someone else will give you a more stable approach....
