Tony runs afterschool project

[kathrum.livejournal.com]

Hello. I'm trying to find a fic I remember reading a few months ago in which Stark goes to an after hour program at a school to help kids learn to design/build. He even brings one of his robots to help run the class. I'm fairly certain it was a Steve/Tony fic as well, but might not be. I know that is extremely sparse on details, but I'm hoping someone might have an idea of what it is. Thanks!
