Gravity Engine is a series dedicated to the idea that while we constantly communicate we simultaneously fail to communicate by some amount—a degree of failure that can be represented in some way. Available for the first time here as an NFT, Horizon of the Mind/Atheist Prayer Wheel, highlights the elusive nature of experience and the tenuousness of rational aspirations in the face of an uncertain future, drawing a comparison between the cyclical character of computer algorithms and traditional prayer wheels.
