We're watching the eclipse at work. I brought some binoculars today and have the rigged up in the company kitchen projecting a sun the size of a CD on to a whiteboard. Very cool. It has a good sized bite out of it right now and is supposed to go up to over 70% coverage around 6:15PM PST.
My favourite eclipse effect is the scattering of mini-suns you got in the shade under trees. The spaces between the leaves create tiny pinhole sized gaps that project a slighly blurry image of the sun. During an eclipse each of those blurry spots has a very distinctive bite out of it.
