The rules are simple;
I'll start by adding a picture of a puzzle (either the full picture or just part of a picture or maybe even a distorted picture) and you have to guess what it is and name it in this thread.
If you get the name right then it's your turn to post your picture of a puzzle for other people to guess.
Wait for your guess to be confirmed as correct by the person who posted the picture before adding a photo of your own.
Don't post any pictures of standard burr shapes though, or one round could go on for months...

Now, here's the first picture:
Anyone know what it is?
