Céphéide is a device created in 2020 by Graphset. This tool born of a desire to explore new forms of narrative expression by superimposing ephemeral photoluminescent images.
The term narrative is to be understood in its broadest sense. It does not necessarily mean a story with a beginning, a development and an end; rather, it's a question of relating images of images on the same plane of projection in a given timeframe, the together produce a narrative development.
The device consists of two main elements:
- A phosphorescent panel that re-emits light at points where it is
where it is exposed to a light source,
- A bar of LEDs (pixels) moving on a horizontal axis.
By decomposing an image into a series of vertical strips one pixel wide pixel width, each strip can be "re-projected" at regular intervals onto the at regular intervals onto the photoluminescent surface to recompose the the original image.
