About Poleidoscope
Poleidoscope is a live camera-effect app that visualizes rational functions of complex numbers. It displays a rectangular region of the complex plane and lets users place roots and poles on the screen. The resulting function transforms the camera image, bending and shifting it into kaleidoscopic patterns. Users can interact directly with the display, without needing to understand the mathematics behind the effect. For people studying complex analysis, the same interface offers a visual way to explore complex polynomials and rational functions. The app can help illustrate how holomorphic functions map regions of the plane, including concepts such as conformal mapping, local behavior near roots or poles, and related theorems. Poleidoscope combines an experimental visual filter with a mathematical visualization tool. Its effect is based on the selected mathematical structure rather than a fixed set of image filters. The evidence does not specify saving or exporting the camera output, so the documented use is a live interactive view for artistic exploration or mathematical intuition.
