Glass Floors: A New Perspective on Windows

"Glass Floor [Pics]" at ArchiBase.net.

People visiting the Spinnaker Tower in Portsmouth, the the CN Tower in Toronto, and the observation deck of Sky Tower in Auckland, obviously enjoy looking down, past their feet, through the floor, to an array of glass, steel, concrete, and other hard materials tens of yards below.

I'd probably enjoy the experience, myself, but wouldn't recommend it to someone with vertigo troubles.

The caption above the first photo reads, "The view through the glass floor in the Spinnaker Tower" - and that's the only caption I saw. Judging from what's below the floors in the dozen-plus photos, they weren't all taken at the same place.

The page is worth a look, though.
