Josh Buczynski runs the site Paper Poseables, which - ironically enough - features poseable paper toys. These are all Josh's designs, and he offers up a number of free downloads like Bachsy and Facebot.

One of the cool thing's Josh has developed is a new interlocking system he calls "Poplocks". They are available (with a paper toy template) in his online shop. Also, you can download a sample via his website.
