The cursor has mass
Every star samples a softened point-lens map. Move slowly and the field curls into arcs around you.
Hero Experiments · gravitational light
Move through a deep star field and watch light bend around you. Increase gravity, lengthen the exposure, then trigger one impossible pulse.
self-contained canvas · touch-safe · no animation libraries
Every star samples a softened point-lens map. Move slowly and the field curls into arcs around you.
The trail control changes canvas persistence, turning clean astronomy into long-exposure calligraphy.
Pulse briefly swells the Einstein radius, then lets the field settle back to its chosen gravity.
