Hy friends it's me 
I took my time hunting for shadows this morning. Then I found this beautiful shadow. Can you guess what thing is making this shadow? It can be hard to guess since I modified the photo that it is why it looks like that.
It is a shadow of the handmade by my son many shapes to make it triangle, circle, half circle, square and rectangular. To make it more interesting, I edited it by adding effects like mirror effect.
