What do you do with old posters?
In academia, it is common practice to make posters of your abstracts for national conferences. Once you are done presenting, what DO people do with the posters? I have several posters rolled up in my garage collected over the years.
If the answer is nothing, why can’t we find a more creative way to display static (or even video) content during abstract sessions? Perhaps use a large LCD screen instead of posters taped to a backboard?
Patients often come into the ED for eye pain. One of my favorite procedures is removal of a small foreign body embedded in the cornea. There is a great instructional video on removing such foreign bodies and the use of a ophthalmic burr on removing rust rings.

A 6-year old boy has placed a hard bead in his ear and presents to the ED for care. How do you remove this foreign body as painlessly as possible? You can just barely see the edge of the bead by just looking at the external ear.
