everyone is deleting the caption to this but this work is called “perfect lovers” by the gay artist felix gonzalez-torres. the piece is about the illness and death of his HIV-positive partner ross laycock:

For Untitled (Perfect Lovers) (1991), he synchronized two industrial clocks placed side by side. Inevitably, because batteries fail and things tend toward entropy, the clocks would slowly begin to advance at differing rates, out of sync, having moved, however briefly, perfectly together. (x)

“Don’t be afraid of the clocks, they are our time, time has been so generous to us. We imprinted time with the sweet taste of victory. We conquered fate by meeting at a certain time in a certain space. We are a product of the time, therefore we give back credit where it is due: time.
We are synchronized, now and forever.
I love you.”
(Gonzalez-Torres, 1988)
