I imagine that someone would be unhappy about this being posted here, but I don't see anyway else that anyone could get a hold of this.
This is MediaText. It runs on Mac OS 9 and runs fine in Classic mode on OS X. It's a multimedia composition environment for kids. Write text on the left. Make media in icons on the right. Move the icons around, then scroll, and the icons stick next to the text. It supports doing recorded sounds, animations, graphics, movies, etc.
