Moosecandy was a plugin that did this, though there may well be another..
There are many posts on how to do this, basically add a counter to your loop, then check for the counter value, when it reaches a certain number, echo the adsense code.
Example, http://ww.wp.xz.cn/support/topic/19519
Since I was one of the original people helping out with placing ads in the templates, I decided to make a plugin (that should be out this weekend) that’ll let you specify locations for generating echoes or includes between posts on the page. Should be pretty darn simple.
I’ll try to remember to post here when I release it. 😉
