BILL – Never-ending plane in the sky by Emmanuel Le Cerf

Created by Emmanuel Le Cerf, BILL is a simple paper bill, one piece of material supposed designed to last the long-term, which gets turned into a never ending animation. Originally white, this paper becomes blue when touched by heat. If over-exposed to heat, the paper is totally blue. If a new heat comes close to the blue paper, it lets a white and ephemeral mark.

Bill is kind of a “mechanical cinema”. I tried to divert the heat paper mainly used as a basic bill. Its chemical properties struck my mind as I realized this material could become something different with a few operations. The paper becomes blue where it has been overheated. Afterwards, it becomes possible to actually mark it: a new contact with heat colors the paper back to white, a mark which ends up by vanishing after a few second tenths, which is a real paradox since a bill is supposed to be a long-lasting proof.

The mechanism makes the paper strip go round through the window of a large white frame. The strip grazes a hot iron point. This short contact creates a white mark in the blue, a mark which lasts for a short while. It creates a never-ending travelling plane in the sky.

BILL was created in Digitalarti’s Artlab.
