I'm not going to attempt to review Gaelcon - if you're looking for a good review I'd suggest heading on over to Ireland's top gaming podcast, The Adventuring Party. I'm going to take the much lazier approach of just sticking up a few photos, below.

These guys have an interesting system; players are rewarded (over time) with in-game benefits for improving their costumes. Result: lots of accessories. Imagine if office workers had this sort of incentive system...
As well as playing LARPs I also encountered a group of people who play a truly weird sport called Jugger. It's based on the post-apocalyptic film The Salute of the Jugger and sounds like a cross between American football and gladiatorial combat. I must investigate this further.
The reason this photo is a bit blurry is that this guy is whirling a foam-padded ball-on-chain type weapon around as fast as he can.
