What really excites me..

Yesterday I went for a 5 hours walk through brooklyn down and the downtown. Finally I also crossed the brooklyn bridge. There are some areas of brooklyn like Bedford Ave which are really cool, it has nothing to do with the rest of New York! But a part from all this turistic stuff, what really excites me are things like this glass. I think it is really cool.

Basically if you look through the glass from with a trasversal vision, you see everything. And you can notice that at the beginning you can see the small desk on the left side of the room behind the glass. But then as soon as you change the angle and you look thourgh it with a diagonal incidence, the glass shades!
Another thing that excites me and i need to discover are the mechanics of a combination lock.
