 * [Joseph Parker](https://gist.github.com/selfsame) wrote a WFC [tutorial](http://www.procjam.com/tutorials/wfc/) for Procjam 2017.
 * [Aman Tiwari](https://github.com/aman-tiwari) formulated the connectivity constraint as an [ASP problem](https://gist.github.com/aman-tiwari/8a7b874cb1fd1270adc203b2af293f4c) for clingo.

+* [Sylvain Lefebvre](https://github.com/slvn-lefebvre), [Li-Yi Wei](https://github.com/1iyiwei) and [Connelly Barnes](https://github.com/connellybarnes) are [investigating](https://hal.archives-ouvertes.fr/hal-01706539/) the possibility of hiding information inside textures. They made a [tool](https://members.loria.fr/Sylvain.Lefebvre/infotexsyn/) that can encode text messages as WFC tilings and decode them back. This technique allows to use WFC tilings as QR codes.
 
 ## How to build
 WFC is a console application that depends only on the standard library. Build instructions from the community for various platforms can be found in the [relevant issue](https://github.com/mxgmn/WaveFunctionCollapse/issues/3). Casey Marshall made a [pull request](https://github.com/mxgmn/WaveFunctionCollapse/pull/18) that makes using the program with the command line more convenient and includes snap packaging.
