Flight Path Comparison
v2.0
Compare globe route distances with a flat-earth map distance model on the same city pair.
Fisheye Lens Horizon Simulator
v2.0
Simulate how a fisheye lens can bend a straight horizon in wide-angle footage, especially when the horizon sits away from the image center.
Crepuscular Ray Perspective Comparator
v1.6.1
Compare parallel sunlight, anticrepuscular convergence, and a nearby-lamp contrast to explain fan-shaped sky rays with perspective geometry.
Map Distortion Comparison
v2.0
Measure how the flat-earth disc stretches east-west distances at southern latitudes.
Sun Path Comparator
v1.2
Compare a standard globe Sun path with a simplified nearby-sun flat-earth dome model and test how their daily predictions diverge at the same latitude and date.
Debunks

Flights Only Make Sense On A Flat Map
v1.0
Real airline routes only make sense on a flat-earth map, especially in the southern hemisphere.
Antarctica Is An Ice Wall
v1.0
Antarctica is not a continent around the south pole. It is an ice wall around the edge of a flat Earth.
Sun Rays Prove A Local Sun
v1.0
Crepuscular rays show the Sun is nearby because the rays spread out visually through clouds.
Compass Bearings Do Not Prove A Flat Earth
v1.1
A compass points north on a flat map, so that must mean the Earth is a plane centered on the north pole.
Flat-Earth Map Distortion Does Not Matter
v1.0
Any map has distortion, so the distortion problems in the flat-earth map are not a real objection.
