Simple Fluxus sketch. Fluctuating colour pattern made with perlin noise. Fluctuating opacity with snoise, generating a nice pattern. Zooming the camera into the layer of cubes and pointing it towards the edges or corners makes some nice perspectives. Variation of https://gist.github.com/jsilence/5411516
