Abyme
A field guide to an infinite coastline, for iPhone and iPad.
Press and hold to fall into the Mandelbrot set. Abyme computes every pixel live on your device and stays sharp far past the point where ordinary arithmetic gives out. Watch a Julia set morph as you drag, find hidden miniature Mandelbrot sets, read what you're looking at in a hand-written field guide, and turn your dive into a zoom movie or a wallpaper. No account, no ads, no tracking.
