I'm not an artist nor am I an art critic, but I appreciate beauty.
There's a beauty to a quickly made creation that is not meant to last. That is ephemeral. That is imperfect.
Like a sand castle that will soon be washed or blown away. Or a chalk drawing on the sidewalk that will be rinsed off or stepped on. Or an improvised melody that wasn't recorded. Or splashes of powdered color during a festival like Holi. Or a design created with milk on top of a cup of espresso.
These ephemeral art don't last and soon are forgotten except when captured. Through a photograph, through a drawing, through a video. What is incredible is how little time and effort it takes to create beauty.
The trained hand lays down chalk lines and milk froth, focused in the moment. Then it moves on, detached from the result.
