In 2011 the volume of available data is predicted to continue along its exponential growth curve to 1.8 zettabytes. (A zettabyte is a trillion gigabytes; that's a 1 with 21 zeros trailing behind it.)Which I guess is why Chris sounded so surprised and delighted by his own statement. We'd just heard from Mattias Astrom, whose company digitally maps the world's cities and every building in them in gloriously faithful three-dimensional renderings. After that, the digital artist Aaron Koblin explained how he visualizes massive data sets (for instance, by tracing every flight in North America and then breaking down the data by time, type of plane, altitude and so on, and presenting it all in a sequentially spoolable rendering that is both revelatory and beautiful). Koblin specializes in crowdsourced projects, such as a Johnny Cash music video drawn by thousands of strangers, frame by frame. The level of detail is breathtaking; one fan lavished 31,000 brushstrokes on a single frame. And because this is digital space and each frame's creation is recorded and cataloged online, you can watch every stroke, just as each artist drew it.
