Kinexel (kinematic cell) is a concept developed by an artist Joo-Haeng Lee in 2015.

As a computer scientist, he studied the mathematical principles of digital graphics and as an artist, he noticed the ability to express intricacy through the overlapping of simple geometric elements, namely line segments. Similar to pixels being the basic units of a 2D image, he defined the line segment that becomes the element of a picture as a "kinexel" (kinematic element). "Kinexel Moon" (2015) is the first experiment in the Kinexel series. By overlapping numerous line segments connecting two points with various textures, he depicted the shape of the moon. It could be quickly drawn with a simple computer code, yet the texture revealed depth, resembling analog paints or pens. In the midst of complex research, the artist found solace in the image of the moon, quickly drawn through coding. It is the beginning of the "Coded Paintings" series and one of the representative series.
