Press 📷 to choose a video source.

Press 🌈 to switch between image colors or color table rendering.

There are four rendering modes:

Press 🌀 then drag along the picture to change the fractal (Julia coordinate).

Press 🕂 to pan and pinch-zoom.

Press then tap the picture to start a radial cellular automaton.

Press # to browse saved pics, or upload your own to the shared gallery

Press 🏄 to control the picture by tilting your phone.

🏂 starts tilting; the slider controls sensitivity.

📲 lets you connect other tilting phones.

The menu has a choice of variables to tilt; by default, the Julia c coordinate.

◎ recenters.

In 🌈 mode A, B: adjusts brightness, hue, etc.

In 🌈 mode C, D: custom color table.

+, -: add or remove handles.

Pick a handle to adjust
Position,
Transition type,
Hue,
Saturation, and
Value (brightness).

📌 saves as a favorite.

Iterations: max iterations per pixel.

Colors: number of times the color wheel is repeated between 0 and max iterations.

🌌 returns to the full Mandelbrot set.

🕸 resets the geometry (distortion matrix and tiling).

📷 clears the photo.

Adjusts **c** at each point by an amount proportional to **z**_{0}.

Stretch_{1} | Skew_{1} |

Stretch_{2} | Skew_{2} |

To produce a **Tile** effect, we can quantize before (row 1: real and imaginary) and/or after (row 2) multiplying by **Distortion**.

Rhythmically varies the Julia coordinate.

Generates radial patterns based on Wolfram's elementary cellular automaton rules.

The automata are developed in all four directions according to the scheme by Daniel Reynolds (SCANTRON).

The seed is a 3x3 square which presents 3 seed cells in each direction. To present the same seed in all directions,
we repeat [a] [b] around the perimeter, where [a] and [b] are user-configurable. In the traditional downward direction,
we can start the seed row with [a] (bind left) or [b] (bind right). Offset 0 sets a cell based on the three cells directly
above it.

If you have modified the fractal geometry (stretch, skew), active cells morph to show the fractal without distortion.
