This week will be a bit eclectic 😉. We’ll consider the various forms in which we encounter local data out in the wild — from community bulletin boards to billboards, public interactive kiosks to wayfinding graphics, street signs to stickers. What kinds of explicit and implicit “data” are conveyed through these media? If the weather’s nice, we’ll do a little fieldwork and documentation outside, off campus. We’ll also consider whether it’s possible to cultivate a sense of localism online: can we create, say, digital neighborhoods or data gardens?
