This site allows you to vote for the “new” 7 wonders of the world. I found it through Pejman Yousefzadeh via Pajamas Media.
My seven are (one to seven) 16, 15, 20, 9, 7, 14, 6. What are your seven? It starts easy with the Giza Pyramids, Taj, etc. Narrowing down the last three is much more difficult.
