Using rice flour, found shapes on the pavement that resembled full stops were intervened to momentarily appear as a comma, colon, dash, semicolon or hyphen. After the punctuation marks are made, they slowly disappear because of the wind or people walking over them.
The punctuation marks – whilst setting an order, pauses, transition and rythim to what's in between – represent the ephemeral nature of time and passing moments, where the only certainty is an end (death), hence the full stop.
