This guy on NeoGAF is a genius: "I think I know what Bungie (or their PR company) has done (or are trying to simulate). The terminology being used in this teaser is very similar to that used in radio interferometery, a technique where signals from individual radio telescopes are combined electronically to produce highly detailed images on the sky. Collections of such telescopes are called "arrays" (like the Very Large Array in New Mexico). A given telescope is sometimes called an "element." Pairs of telescopes in an array are "baselines." In a radio interferometer, signals from each pair of telescopes are interfered and the resulting product, a "visibility," is measured. A given pair of telescopes produces a measurement in spatial frequency space, the "uv-plane." The ensemble of visibilities are Fourier transformed into an image. What I think may be happening is that every visitor's IP is being traced and the distances to other IPs being worked out, making "baselines" from which an ensemble is being used to slowly reveal the image on the left as more people check out the page. The image on the right is the distribution of spatial frequencies so far covered. As the image on the right becomes more white, with more page views ("global observatories"), more spatial frequencies will have been covered and the image on the left will become more legible. The "frequency gaps" noted beneath the image on the right indicate that the spatial frequency coverage is not uniform, leading to significant aliasing and artifacts in the image on the right."
