What Is This? – III.

Let's see more of your "mysterious" images! Take a photo of something unusual, or of something usual in an unusual way. Don't submit previously entered images; show us something we haven't seen yet. Present your object sharp and clear (blur is no "mystery", just hard on the eyes)! Then go see what the other Entrants' images show, and type your suggestion in the Comment field below their images. At the end of Voting period, each Entrant should explain their image for what it is, so we'll see who managed to guess correctly. ATTENTION: Please observe all the rules! If your image is DQ'd, all the added comments will go too. So PLEASE DOUBLE-CHECK that everything is correct BEFORE submitting your work!
