My department every year has an Art and Science show (This year it is the 4th Annual IB Art & Science Show, April 25, 2008. 5PM in VLSB. Open to the public, food and drink provided.)
Submissions are supposed to be artworks inspired by, related to, or otherwise modified by science.
I was thinking about what to submit when someone (alias Plastic Devil Ducky) posted a bag of Legos on Freecycle. So my submission will be a Lego rotifer (with egg). The difficult part was finding pieces from a pirate ship and a space station that could be made to look like cilia.
