A small(pun intended) game

[Ryan708]

So, I am going to post some crops of some random macro shots I took this evening with my 50/1.8+25mm Kenko extension tube, and you guys make your best guess at what The shots are of. After a few people guess, I will post the full image, or explain or both. Have fun!
I think I shall do 4 at a time for now, I have more.
