Different buildings an regions of New York city shot at different points in time, then layer and synchedideo artist Julian Tryba. To wit:
Traditional time-lapses are constrained by the idea that there is a single universal clock. In the spirit of Einstein’s relativity theory, layer-lapses assign distinct clocks to any number of objects or regions in a scene. Each of these clocks may start at any point in time, and tick at any rate. The result is a visual time dilation effect known as layer-lapse. 1 Film, 22 Trips to New York, 352 Hours of filming, $1,430 paid in Parking Fees, 9988 Miles Driven, and 232,000 Pictures Taken.
