Information designer Nick Felton probably needs no introduction here: besides his current dayjob at Facebook, his perennial reports have offered a unique window into one particularly astute designer's life as a sort of digital-age diary par excellence.
Yet insofar as the designer himself is the subject of his report, the document contains a mind-boggling amount of raw data on a full gamut of otherwise mundane activities. That it's beautiful goes without saying; in fact, the visual and typographic presentation is arguably more significant than the content itself, at least to the extent that Felton's day-to-day activity consists mostly of enjoying coffee, riding the subway, spending time with friends and family, etc. In other words, he's just a regular guy... who happens to rigorously record his daily activities and compile the data in a brilliant artifact.
Which is to say that the Feltron Report is, as always, well worth closer examination (why summarize a summary?); the Dieter Rams shout-out—"Best Celebrity Encounter / at NYC Vitsoe Shop"—is just one of many hidden gems.
