coincidence/incidence/interference is a series of drawings that explores the layering of information into a composite reading of both the physical and the virtual. in this collection of hybrid drawings/vizualisations, we leverage the overlay as an opportunity to explore graphic representations which have a multiplicity of layers and readings as a technique for generating moiré effects. we are interested in the superimposition of multiple patterns of information (be it figural or literal) with the intent of discovering an emergent generative effect, completely defined by the perceived coincidences, incidences, and interferences produced by their overlay. the combined effect is not an addition or subtraction of the two patterns, rather it is an exponential multiplication of their effects. the emergent pattern is one which not only implies movement, it is activated by it, as the moiré effect is brought to life by the variable relationships between the two original patterns and the shifting perspectives and perceptions of the viewer.
