Number 3, refined. Four seats round a table top, seen from above, one of them yours. Everything below changes one number at a time — how big the table is, how big the seats are, how far out they sit, how round their corners are, how much of the frame it fills, and how many are at it. Number 1 is the original, unchanged, to measure the rest against. Say which is best and I will ship it.
The same fifty on a light ground, at 48px. A mark that only works on one is not a mark.
