This is code for performing the WaveFunctionCollapse algorithm on poems. It mashes up sentence fragments from a given corpus to produce poems with fixed metric forms. It can also animate the process:

It is named after Oisín, son of Fionn mac Cumhaill, the great poet-warrior of Irish mythology. He famously married Niamh, daughter of the sea god Manannán mac Lir, and disappeared over the waves to Tír na nÓg. Waves, poetry, etc, you get it.

The name is pronounced [ɔ'ʃiːnʲ] (ush-EEN).

This is experimental code, for an experiment that I never really finished.

The code is available under the MIT license, so you can fork it, improve it, learn from it, build upon it. However, I have no interest in maintaining it as an ongoing open source project, nor in providing support for it. Pull requests will probably be either ignored or closed.

If you do make something interesting with this code, please do still let me know! I'm sorry that I can't provide any support, but I am still genuinely interested in seeing creative applications of the code.
