What should I do with the 21 USB memory sticks in my desk drawer?

Load each with a single text file that contains a) your name, location, and the date and b) an invitation for people to add their name to your list and place the USB drive in a random public location.

Label each with a tiny sticker that says "Private: Do NOT Read!"

Place each in a random public location.

What I did (with fewer sticks):

Copied whatever pdf files I found useful as a startup (example incorporation templates, cautionary tales, relevant essays, useful tips etc.) onto them & passed them on to whoever wanted them. Great feedback so far - although that wasn't the goal.

There's got to be some kind of art project you can do with this.

Here's something done with toothbrushes, for inspiration. http://www.georgehart.com/sculpture/just-two-cavities.html

http://recycleusb.com/ will turn them into bootable drives with Sugar (the OS developed for the One Laptop Per Child project) and donate them to elementary schools.
