Coffee Art?

After watching the movie called, "The Green Hornet," I suddenly was in awe of the way people make their coffee. I picture it as some form of art, knowing that there isn't a very clear deffinition of what art is and all. After looking up some images of coffee art on the internet, I saw that with a lot of practice, you can pretty much create any image in simply something you drink when you wake up in the morning.

You can take a cup of coffee like this:

and turn it into something like this:

or this:



So here's my question.... Because coffee is drinkable and you can create art with it, shouldn't it be more known and attention grabbing since it doesn't last as long as a painting would?
