Shadow art

The form and shadow lessons reminded me of the Philadelphia Flower Show from last year where an artist had taken flowers and other objects to create shadow art with them. This is one of his pieces.

I couldn't find the same artist online, but I found another piece that blew my mind because it's one piece that makes three different shadows. 

I have no idea if you could make something like this in AutoCAD, but that would make my life. I love that both of these just look like a mess until you put the right light on them and then they're gorgeous.
