A Specific PyGame

[Michael P. Nugent]

I am looking for a specific "game" that is really a programming 
environment for young kids.

I believe it implements PyGame, and presents two windows: one is a grid 
with some obstacles, and a character that must traverse the grid; 
another is an interactive editor that encourages a learner to write a 
script to navigate the character around the obstacles.

I saw this within the past week, but I cannot remember or discover 
where. I have revisited a number of PyGame related sites, and Googled 
like crazy, but I'm not finding any visited links that are productive. 
I've also extracted everything out of .mozilla/.../history.dat. As you 
can see, I'm looking for a specific answer to my specific query.
