I am taking "An Introduction to Interactive Programming in Python" at coursera.org. From their announcments page:
Week one of the video contest is open For those of you that are interested in helping your peers, the student video tutorial competition is an excellent opportunity. The week one submission thread is up in the "student video tutorial forum." Feel free to browse the current tutorials or make your own. The deadline for submission of this week's videos is 23:00 UTC on Thursday. The overall winner of this competition will receive a $500 tablet computer so give it a try if you are interested! -- https://mail.python.org/mailman/listinfo/python-list
