The Android version of KaleidoPaint is finally finished and publicly available. I would like to share this spectacular and free app with the group Broug Atelier for Islamic Geometric Design.
The link for the new Android version is:

While the iOS version remains at this link:

Here are a few sketches I’ve done with this app, based on Eric Broug’s helpful book: Islamic Geometric Patterns. I am by no means an expert, I’m sure many artists of this type of design can push the app far beyond my meagre attempts.
This tessellation, Mustansiriya Madrasa, is drawn with one single strategically placed line!

The Herat design below is accomplished in KaleidoPaint with two lines, using the symmetry group P6m. Took me a while to figure this one out!
