When I was in college there were many concepts I just could not understand and I wished if I can get someone to help me understand that complex topic. There were just to less of resources available at disposal.
World seems to have changed a lot, thanks to internet.
I found this interesting site today http://academicearth.org/ thanks to TechCrunch, which hosts loads of free to watch video lectures from subject matter experts. Astronomy, Engineering, Computer Science, Political Science..you name it.
Its such a great resource for faculties. Its a great resource tool for them to explain concepts. Just grab that not so much used auditorium and play these videos.
Sounds fun and productive.
