Waves are crashing against the shore on the surface of a mug. They start off dark, slowly turning lighter as sea foam emerges.
A hand reaches for the handle to take a sip from the green ocean. The opposite hand curls itself around the mug like Poseidon holding the sea. The ceramic is as smooth as water gently flowing from a tap.
A river starting high from the mountaintops makes it's way from the narrow top to its wide, new, salty embrace. A gulf is an artist mixing their blue paint trying to get the perfect shade and balance. A gulf is an artist dipping their used paint brush in clean water and watching the colors swirl.
A mug is simply glazed ceramic formed into a shape that humans use to drink beverages. Every mug is different from their shapes to their colors. Every body of water is different from the rest.
