Bowman: timewaster of the day

I'm procrastinating and I found a fun online game. It's a well worn theme, like the old catapult games but still fun. The game is bowman and the concept is very simple. You are a bowman (or archer to use the proper name)with a CPU or human opponent. You have to judge the power and angles to hit your opponent. First person to score a direct hit wins. Simple and fun, give it a go by clicking on the picture.
