Stephanie, Colin, and a friend of theirs started this website called Me in Three, which is up but not quite because they're busy changing the URL. When it is up for real, I'll link you.
So, you might ask, how do I take part? It's easy!
1) Grab three things that describe you in some way. You can go the deep route and try to encompass your entire being, or you can go with a theme, like I did in the above picture. (I might do a math one next, actually. Hm.)
2) Take a picture with all three items in the picture.
3) Email it to email@example.com. Include your name (a nickname is fine) and a description of the items. Tell them I sent you.
4) Wait for it to go live on the site.
