I've just recieved my first mac, an iBook G3 600Mhz 384MB 20GB Combo with Mac OS 10.1.2

I've been looking for torrent clients but i cant seem to find any for my version of mac os ! I do not plan on upgrading my software as it is rather expensive and the one i have servers me well.

Can anyone recommend/forward me to any torrent client i will be able to use. I've tried BitTorrent, it mounted successfully however when i click the BitTorrent application icon, nothing happens!

Can anyone help?
