I am working on a poetry generation system, called Bard, which I would eventually like to enable generation of Irish poems according to traditional bardic poetry styles.
It should also handle other languages.

Bard was instrumental in generating the following poem:

It occurred to me just now that Gramadoir could be used to do the checking, the Irish wordnet for synset, etc. So a very good start.
I still would like to find nice libre bidirectional Irish / English dictionaries for learning, such as O'Donnell's Foclair Bhearla Gaeilge, if that's available.
