Girih App

To create even easier ornaments, than with the laser cutted Girih tiles, I decided to write a specialized App for it.

An App has some advantages to the physical tiles:

Physical tiles tend to move around a bit, when you release your fingers or add another piece.

Loose tiles can not be durable stored as ornament.

The number of physical tiles is limited.

The look and size of physical tiles is fixed.

You can not seamless join physical tiles.

Download the Girih App Version 1.6 from October 2017.

Requirements: OS X 10.11 El Capitan or newer

Girih App by Stefan Hintz

This App is completely written in Swift.

As an addition to the standard Girih shapes: Decagon, Pentagon, Hexagon, Bow Tie and Rhombus at added some more shapes.

Not all of the shapes can be combined together without gaps.

So this App is also useful for creating Penrose Patterns or Ornaments from regular Polygons.

I am curious to see, what you create with it. If you tweet about it, tag it with: #Girih

Please let me know what you like about my Girih App and what not.

    Dear Stefan Hintz
    Considering to buy a Mac just to work with your program/app, I am much more willing to pay for an iOS app in App-Store. Therefore; are you planning to create/sell a iOS version of Girih? (There should be many like me that would love to be creative with the endless possibilities of patterns)

    Best regards

    Fridolin Okkels

      I have not started a Girih App for iOS yet.
      I still have so many plans to enhance the Mac version further, so that I am focussing on the Mac at the moment.
      The Mac App is already written in a way that you can work mostly just with one hand, so creating an iOS App should be possible.

  • Hi!
    I think you’ll like my work on Girih tiling. You can find it here:
    (The Girih part comes in part VI)

    Trying to unzip the archive and it’s telling me “no such directory.” Any ideas what folder it’s trying to find? (Running 10.11.6 on a MacBook Pro)

  • Stefan Hintz says:

    macOS 10.11 should work fine.

    Try to download it with Safari.
    Safari will unzip it automatically by moving the zip file into the trash folder and and leaving the App in the download folder.
