Ondřej Rypáček calculates by hand how imaginary rays of light illuminate a sphere on an infinite plane, following Lambert’s principle (1760). The results are transferred onto a grid, creating a pixelated image through a painstaking process in which human execution inevitably departs from mathematical precision.

Rypáček questions the privileged role of spontaneity, intuition and gesture in art. Drawing on Sol LeWitt and Vera Molnár, he separates the conception of a work from its execution, exploring creativity, authorship and the relationship between human agency and machines.

Ondřej Rypáček holds a PhD in Theoretical Computer Science from the University of Nottingham and worked as a research scientist at the universities of Oxford, King’s College London and Sheffield. He later completed an MFA at London Metropolitan University. His work spans painting and photography, and has been exhibited with Vivienne Roberts Projects and elsewhere.
