This is an HTML5 Canvas port of the "Irregular Grid Painter" (IGP) application by Zlosk. You can find the original IGP here http://www.zlosk.com/pgmg/igp/downloads.html. Zlosk has (quite reasonably) requested that any derivatives of his work call themselves something other than simply "IGP" to avoid confusion.
If you would like to easily run a local instance, run the following python command in the canvas-igp root directory (replace [port] with your desired port number):
python -m http.server [port]
Then point your web browser at http://localhost:[port]
Obviously its a docker image so you need docker, if you don't know what that is you need to look into that first.
docker build -t canvas_igp .
docker run -dp 8000:8000 canvas_igp
