I love little round cactus plants. They remind me of cute little hedgehogs. That's why I also like this round cactus dude here. Of course, you don't want to pet any of them. If you do, well, let's just say you'll get the point soon enough. :)
@alophoto - Thanks for pointing that out Amanda! For the life of me, i could not get the focus right on this subject. It kept being blurry. I took it to manual focus and eventually got it right.
