We spotted this mosaic-like window at the Zeum this past weekend, and had to move in close before we could puzzle it out. Turned out to be a wall of time capsules, each one the work of a different child: a small fistful of future nostalgia carefully nestled into a glass jar. The overall effect was so striking that we had to snap a pic for AT. We're thinking of all those San Fran flats with a window looking out on the neighbors' siding. A little DIY art installation inspired by the Zeum's time capsule window would provide privacy and improve the view without cutting off too much light.
