Shadertoy Example
=================

One wgpu_shadertoy example written in WGSL, I don't know if this is a port or original work.

    Interactive example
    ===================

    This uses Pyodide. If this does not work, your browser may not have sufficient support for wasm/pyodide/wgpu (check your browser dev console).
    Stdout (print statements) will also appear in the browser console.
