F/11, 131sec, iso200 @ 18mm
PS work: tilt, crop, sharpen, photo filter(for blue), boost of saturation, resize, sharpen again.

I've always wanted to try this out but wanted to put some kind of twist on it.

Toss a small LED flashlight around on a rope attached to something, put the camera under it , point up and fire away is pretty much the technic :) I read if you're using a bigger light source, place/tape a piece of cardboard with small hole in it to the end of the light source.

But really, this shot was a bit more complicated... This one took at least 3 tosses. Between each toss cover the lens with a piece of cardboard, just in case the toss is bad and after each toss wait a bit for the path to smooth out. I applied a PS Photo Color Filter to get the blue hue you see here.
