ζ(½ + it) — the critical-line spiral

Pick any window of t and the page will actually root-find every zero in it live (via the Riemann–Siegel Z(t) sign changes), not just look up a canned list — so you can explore t = 1 – 100, 100 – 1000, or anything else.

t
0.000
Re ζ
1.000
Im ζ
0.000
|ζ|
1.000
Red dot = current point. Green rings = an exactly-located zero within the current window. With Auto zoom on, the view tightens in as the curve nears the origin and pulls back out as it swings away.
Range of t
Windows past a few thousand can take up to ~30–60s to fully scan (runs in the background, won't freeze the page).
