many things about this did not go as planned... however, i am not entirely unhappy with the result...
this is something that has been lurking in my head for a while now... and although it's not a typical halloween shot, i think (hope!) it is creepy, and as such meets my get pushed challenge set by @annied to shoot something that isn't your typical halloween shot, but can still qualify as "halloween"...
Flickr also has examples of vortographs.
Might be fun ... might just be weird. I'm not sure. If you don't have time to play with this, though, let me know and I'll set another challenge.
