To reach the top of the Arc de Triomphe one must climb 260 dizzying spiral steps. Tim and I sprinted up because we were there just before it closed and wanted to have as much time at the top as possible. He thinks it looks like a nautilus. I think it looks like a person with vertigo's worst nightmare.

One other note: It was very dark and didn't have my tripod, so this is a 2s handheld shot. Under ideal circumstances, it would have been a much longer exposure stopped down to get the full DOF with no shake :)

Away on business so this is another photo from France (though I just finally edited it!)
