Natural wonders of the beach

Now I'm breaking my promise not to post very often. It's the beginning of a long journey, so mistakes are forgivable :).

A few words about the pictures: They were taken in August 2007 in Hiiumaa near the Kõpu lighthouse (roughly 5 km to the West). They are few of the more interesting finds from the beach where I was camping.
I really like the first one - it's like miniature rock. The second one has some outer space element in it. The third one represents nature's perfect geometrical skills.
