Fractal Atlas

Fractals are patterns that never run out of detail. Fractal Atlas lets you fly into them with your fingers. ZOOM DEEPER THAN YOU'D BELIEVE Pinch into the Mandelbrot set and keep going, trillions of times closer, with the picture staying sharp the whole way. The Sierpinski carpet and gasket and the Apollonian gasket go deeper still, about a quadrillion times. SURPRISE ME Tap the die to fly to one of 98 named places, from Seahorse Valley to a fleet of burning ships. On the Sierpinski carpet and gasket, it takes you on a spiral dive. NO MATHS REQUIRED Just pinch, drag and twist. The info card tells you in plain words how far you've zoomed and where you are, with a scale bar like a map's. The technical readout is there if you want it. SEE TWO WORLDS AT ONCE Dual view pairs a Mandelbrot with its Julia set. Drag across one and the other follows. Pick a famous Julia set and see exactly where in the Mandelbrot it comes from. 25 FRACTALS AND PATTERNS Mandelbrot, Burning Ship, Tricorn, Celtic, Multibrot, Phoenix, Julia sets, Newton's method, Sierpinski carpet and gasket, Apollonian gasket, Koch snowflake, Pythagoras tree, Hexaflake, Dragon, Hilbert and Gosper curves, Barnsley fern and more. Every one supports pan, zoom and two-finger rotation. Press play and the Koch snowflake, Pythagoras tree, Hexaflake and the dragon, Hilbert, Gosper and arrowhead curves grow and shrink by themselves. YOUR COLORS On the Mandelbrot family and the Julia sets, pick a Look: Edge glow, Stripes, Bands, Orbs, Rays or Relief. Then choose from nearly twenty colormaps, from Inferno and Viridis to Classic and Fire, tune Repeat and Shift, and set how much detail to compute.
