Today's Astronomy Picture of the Day is a nice time-lapse view of the Perseids. You'll see that all the streaks seem to be coming from one central point, the radiant, or the orbital stream of the bits and pieces that make up the "shower". (We all know what happens when we cross the stream, right?)

"Mouseover" the image to get constellation information.
