PBS Kids STOP and GO Stories

So, there was this fun little interactive storymaking tool that used to be on the PBS Kids GO website called STOP and GO Stories. From what I can gather, it came into existence sometime around 2006, and was functional for somewhere in the region of 5 years afterward. I've found a plethora of commercials for the tool on Youtube, and even a half-functional webpage on the Wayback Machine, but for me the trail's gone cold. I'd like to see if any of you can help me possibly getting this thing fully functional again, or at least solid documentation of its operation.
