JETSTREAM is a real-time, interactive map of the world's jet streams. It animates global upper-level winds (their speed, direction and intensity) at the 200, 250 and 300 hPa pressure levels where the polar-front and subtropical jet streams flow, rendered as a flowing particle field over a dark, draggable 3D globe or flat world map. Wind data comes live from the NOAA GFS model via Open-Meteo. Open the JETSTREAM live jet stream map.
SIRENdipity is a free idle clicker game. Crank the siren by hand to earn coins, then spend them on automation and bigger sirens that keep earning for you, online and offline. Play the SIRENdipity idle siren clicker game.
Bullet POV is a ballistic flight simulator where the camera rides the bullet. Ever wondered what happens if you fire a gun straight up? It opens aimed at 90 degrees so you can find out: the bullet climbs over a kilometre, hangs at the apex, then tumbles back down for the better part of a minute. Pick one of 45 weapons, from pistols and sniper rifles to naval guns, trebuchets and the US Navy's Mach 7 railgun, aim anywhere on a real 3D satellite map, and fire. The trajectory uses real exterior ballistics (G1/G7 drag, ICAO atmosphere, wind, even live weather at the firing point) and the flight ends where the bullet actually meets the terrain. Fire a gun straight up in the Bullet POV ballistic flight simulator.
