×Ob

×Ob is a fictional operator and art project used in speculative mathematics and media theory. The name fuses the multiplicative symbol with the letters Ob to signal a cross-disciplinary, cross-observational approach. The concept appears in imagined formalisms and in contemporary art discourse as a way to discuss interaction and perception across systems.

In the fictional formalism called Ob-algebra, ×Ob is a binary operation that combines two elements, a and b, into a composite Ob(a,b). The result is intended to encode not only the inputs but their relational dynamics under a cross-observational perspective. No real-world axioms accompany the operation; it is used primarily as a mental model for how distinct data streams might be juxtaposed and interpreted.

As a contemporary art project, ×Ob investigates data fusion, audience participation, and immersive environments. Projects typically employ generative software, sensor networks, and projection systems to merge live streams with archival material. The outputs are audiovisual installations that respond to viewer presence and environmental context, creating evolving landscapes of form and sound.

Origin and reception: The concept emerged in speculative online communities in the late 2010s and has since appeared in fictional catalog entries and discussion essays about interdisciplinary practice. Critics note its value as a thought experiment about collaboration and perception, while also recognizing its role as a stylized rather than a prescriptive framework.
