I was teaching a Physics class in Brooklyn at the time the eclipse was visible, so I took all the students outside to observe it. We used index cards and the pinhole camera method of creating an image of the Sun, so no one would make the mistake of looking directly at the Sun, which you must never do without protection for your eyes.
The most fascinating observation I made during this eclipse was that the shadows of a tree's leaves also created their own pinhole camera effect. Looking at the ground we could clearly see shadows with a "bite" out of them, similar to the appearance of the Sun during an annular eclipse.
If you want to know more about annular eclipses, Wikipedia has an article on solar eclipses here: http://en.wikipedia.org/wiki/Solar_eclipse
And there's a ton of pages devoted to pictures and observations from the 1994 annular eclipse; here's a few I recommend:
