An hourglass is filled with black ink. The hourglass is turned over every 20 minutes. Slowly, the ink runs out from the top to the bottom, and covers a lamp below, plunging onlookers into darkness. This device literally reproduces an everyday natural phenomenon: the falling of the night. Combining technology and poetry, with this installation Nightfall make us aware of all the experiences this simple and daily phenomenon unleashes on us, whether sensory, cognitive or spiritual.
