Fractal studio — Mandelbrot and Julia

palette preview
Tip: Alt + click on the canvas to sample the clicked complex point and set it as the Julia constant c. Use rectangle selection to zoom, Shift + drag to pan.
All processing runs locally. The Julia set uses the constant c you set. Alt + click to sample c from any point in the canvas. For MP4 conversion use ffmpeg: ffmpeg -i output.webm -c:v libx264 output.mp4
Expect more CPU for large exports and deep zooms.
