Poi
I do a lot of meandering on the internet, somewhat like a cow let loose on the fields. On one such recent excursion i came across 'Poi' - A performance art which originated in New Zealand. It is a traditional art form of the Maori people. Check out this video : How cool was that! All it takes to get started are 2 identical weights tied to 2 same length strings. It is a lot of fun :) I've tried it and can actually perform some fancy moves :) Give it a shot when you are bored. It is not as tough as it looks, but not that easy either. Just make sure you don't take someone's eye out :)
