Unique shower curtains are a wonderful combination of design and function. Functional, because they keep the vinyl keeps the water from ruining your bathroom, and practice because the novelty shower curtain is filled with awesomeness. I love the singing in the rain shower curtain because it is functional in its build but the artwork is interesting. I like how the ground is inferred through the pole and how the character is standing, even though the artist left the ground out. I also think its cool the way the umbrella blocks the water and what is left is a solid white background, as if to imply the blank canvas can be whatever you want to preserve in your life.
I also like mono color they used. Blue and white, about as simple as any shower curtain comes, but this one is alive with movement, space, emotion, and excitement.
