Of course you never want to look at an eclipse directly. Unless you have the correct solar filters, your best bet would be use an indirect means of observing. There are many ways to do this. The simplest way to observe a solar eclipse would be to make a pinhole through some cardboard and allow the sunlight to pass through to hole to a paper. This works but makes a very small image. For today's eclipse we rigged a pair of astronomical binoculars by allowing the sunlight to pass through the large end and projected it on a piece of white paper. We could even see sunspots using this method. Here are some pictures of what we could see from the Phoenix, Arizona area:
My favorite way of observing an eclipse does not require any equipment. All you have to do is look around you. As light gets filtered through tree leaves, blinds in your home, and other small pinpoints of light, crescents appear around you. This is an actual image of the eclipse, similar to the way the pinhole viewer works. Here is an example on my neighbor's house where the sun's crescent appeared everywhere:
The blinds in my house were also allowing just the right amount of light to allow multiple little eclipses on the wall.
