For whatever reason, the spires are counted on those, but not on the Sears tower.
Communication antennae, like those on the Sears tower, are not counted towards the total height of the building. However, ornamental spires, like those on the Petronas Towers are counted.
CN Tower, Toronto Canada. The CN Tower is 553.33 m (1,815 ft, 5 inches) tall
CN Tower still is the tallest free-standing structure, but was never the tallest building. Buildings have usable floors all the way to the top. The CN tower does not meet this qualification.
Not really. There are a number of ways to interpret three dimensions. One is to use two devices slightly distant from each other on which a single three dimension image is projected from two different angles (i.e. two human eyes.) The other is to move a single two dimension device over time (time is a dimension after all) to make 3 dimensions. So, unless the original poster stands completely still all of his life, he can still sense depth and the device in the article wouldn't be as unuseful as expected.

THEN THE ONE MENTIONED HERE ISN'T, EITHER: "The full height was achieved after adding a 60-metre (197-ft) spire on top of the building"
Correction, "all the way to the top, which may include an ornamental spire." I was talking about the difference between a structure and a building.

wouldn't that mean you have no depth perception?
