When I first saw this as a thumbnail I thought you shot an out-of-focus macro of broken wire (granted, I was seeing it on my iPhone) but, as Tick always says, we have to enlarge to appreciate. This is some wild looking cactus alright, and I�d hate brush up against it; those ultra fine spines would be like grinding glass insulation into my skin. Makes me grimace just looking at it; a true litmus test of success for any photo.
If you've ever wanted to make a difference but found it hard to believe that one person could... check out the Kiva Team Caedes discussion thread and discover that anything is possible.
