All good things must come to an end, indeed. The fabulously colourful and cartoonish exhibition 'All Good Things..." by artists Timothy Berg and Rebekah Myers focuses on this fact. I also like the descriptive text found on Timothy Berg's website:
Sometimes things disappear as the result of an accident.
Sometimes neglect causes things to disappear.
Sometimes things are intentionally made to disappear.
One’s understanding of disappearance is the result of a specific perspective. In reality most things do not disappear they simply transform. When they are transformed beyond recognition they are said to have disappeared.
