Holler Sydney: The Haeckel Clock IPad App

The Haeckel Clock, as it's known, uses sketches of Radiolarians (ancient single-celled organisms with intricate mineral skeletons) from Haeckel's famous book Kunstformen der Natur or Art forms of Nature as units of time.

One of the app's developers, Lukasz Karluk explains: "The Radiolarians vary in size and as they get bigger, the unit of time they represent also increases. With every passing second, the Radiolarians re-arrange themselves into higher groups, creating unique and ever-evolving forms of time. We like to think of it as our own, very humble version of evolution."

"Ernst Haeckel had a unique, artistic way of looking at the world," says Holler's founder and Executive Creative Director, Mike Hill. "This app is our ode to him and his pioneering work. He has inspired us and, in turn, we hope our Clock inspires others to find out more about him."
