A friend sent me an email that was bare except for the link to a Flickr
page, and now I understand why she didn't write anything to accompany
it - it's hard to think of anything intelligent to write about Alan Jaras's
Bending Light and
Taming Light collections of photos.
They are phenomenal. And beautiful. And very clever.
So, instead of trying to explain how they work (he does that on his Flickr page) or think of some artsy description for them, I'll just offer you the link. There is much more at
flickr.com/photos/alanjaras.
