I decided to not add any taglines, captions or wording and leave this as a pure image.
I was, however, thinking along the lines of "brilliance in a cup".
And I pictured these words on the left-hand side of the image, with the '2' of 'mc2' in superscript:
T = mc2
[Einstein got it wrong.
He'd skipped his morning Tetley.]
Sheer brilliance in a cup.
