"The Cave" is an interactive, projection-mapped installation that explores the dawn of art created by artificial intelligence- art made possible by new machine learning algorithms. By tweeting images to @paintingthecave, the audience spawns algorithmically-generated computer "cave paintings" that are embedded into the cave's digital mesh.
For the tech savvy: the program employs convolutional neural networks to preserve the semantic content of the original tweet while rendering the image in the style of another (also algorithmically-generated) picture. For a complicated, in-depth explanation of neural-style art, check out this paper.
