This guy is the best. He uses a mix of digital and analogue techniques with vivid colour to make your eyes melt. His live projections are out of this world, hypnotising and inspiring. I know that he uses a mix of After effects digital videos, then synthesises them through video mixers and plays these live along with the music. These are a couple of examples of his simpler videos, using mostly After Effects dissolve and displacement effects along with interesting fades. I love the mixing of technology and the melting of my face.
