I've met some very nice people while I was at Ireland, some of them MVPs and quite brilliant (and good drinkers!)

Take for example, [Eamon O'Tuathail](http://www.clipcode.biz/workshops/dsl.html) , who created a small Domain Specific Language for some of the most common Gang-Of-Four design patterns out there, [fully downloadable](http://www.clipcode.biz/workshops/dsl.html) with source and all. There's a nice discussion on this package over at another one of the Irish developer's blogs - [Claudio Peronne's blog](http://developers.ie/blogs/cperrone/archive/2005/08/08/1585.aspx).
