Oh! The magic drawing app

Oh! is a magic drawing app! Moves colored shapes on the screen and looks at the drawing that appears. A single form hides several drawings. Depending on its position or rotation it will turn into a dog, a snowman or a cloud!
From the book "Oh! Mon chapeau "by Anouck Boisrobert and Louis Rigaud, published by helium, France (UK : "That's my hat!", Thames & Hudson).
