Fraqcel (active channel)

Deep-zoom fractals rendered entirely inside Microsoft Excel.

Fraqcel is a free, open-source fractal generator built in Excel, with no add-ins or installs. It uses arbitrary-precision math, perturbation, and series approximation to zoom far past where ordinary floating point breaks down, with optional C# DLLs for multi-threaded speed.

On this channel:
-- Deep zoom videos into the Mandelbrot set, Burning Ship, and more
-- Tutorials on exploring, coloring, and exporting with Fraqcel

Created by a mechanical engineer who wanted to see how far a spreadsheet could go.
