Hmm, interesting. My initial reaction was, "I don't think in black and white, I think in positive and negative space," and believed the premise was flawed. And obviously, using color as hierarchy is not a new idea, nor do fonts inherently limit users from using color.
But it's not too hard to imagine more than two dimensions to glyphs (yes, to an expert this is simply a fancy way of saying layers, and they will still register two-dimensionally). Despite the declarative tone, as a purely conceptual piece, it's an exercise that yields some intriguing results. I doubt we'll be changing how we read anytime soon, but a little typographic exploration can be an amusing diversion.
I've been working exclusively from home for over a year now. For many years, I went into an office, but spent a day or two working from home each week. I found it easier to stay focused in the office, and I enjoyed the company of my coworkers.
Weirdly, though, when I had a very tight deadline for a project, I would work exclusively from home. Commuting would take too much precious time. Once I got into work mode, it was easy to stay in it.
After years of experience, I am able to stay focused while working at home. But it can be too isolating, especially in the winter.
I generally prefer listening to conversations when I work, instead of music. I put on a TV show or movie that I've already seen, so I'm not distracted by what is happening.
After years of wearing headphones in the office, I have a Pavlovian response to putting them on that makes me ready to work.
