The pixel font circa 1567 is cool, but more interesting is Jonathan Hoefler's assertion that the pixel is nearly dead -- except as a design cliche.
The pixel will never go away entirely, but its finite universe of digital watches and winking highway signs is contracting fast. It's likely that the pixel's final and most enduring role will be a shabby one, serving as an out-of-touch visual cliche to connote "the digital age."
Over at H&FJ, the H talks about the &.
As both its function and form suggest, the ampersand is a written contraction of "et," the Latin word for "and." Its shape has evolved continuously since its introduction, and while some ampersands are still manifestly e-t ligatures, others merely hint at this origin, sometimes in very oblique ways.
He goes on to describe several ampersands they've designed for their typefaces. When designing the ampersand for Silkscreen, I came up with a solution that many continue to dislike:

If you're logged in to Flickr, you can see it action at a more appropriate size in the "prints & more" label above a photo. The symbol is basically a capital E with a vertical line through the middle...an e-t ligature that's really more of an overstrike. I fashioned it after the way I hand-write my ampersand, which I got from my dad's handwriting1. I don't know where he got it from; it's not a common way to represent that symbol, although I did find a few instances in the list of fonts installed on my computer.
I didn't think about this way at the time, but the odd ampersand is one of the few distinguishing features of Silkscreen. There's only so many ways you can draw letterforms in a 5x5 pixel space so a lot of the bitmap fonts like Silkscreen end up looking very similar. The ampersand gives it a bit of needed individuality. (The 4 is the other oddish character...it's open at the top instead of diagonally closed.)
[1] Now that I think about it, I borrowed several aspects from my dad's handwriting. I write my 7s with a bar (to distinguish them from 1s), my 8s as two separate circles rather than a figure-eight stroke, and my 4s with the open top. Oh, and a messy signature. ↩
Jonathan Hoefler on how a joke version of OCR-A with swashes came about...and then ended up in an issue of Rolling Stone.
I tacked this specimen of Estupido Espezial!!! to my wall, where it immediately became a litmus test for visitors. Most people would say nothing, but woe be unto anyone who admired the thing in earnest: "hey, cool font!" would immediately land any visitor on the Suspicious Persons list. The best were those who would stare for a moment with bafflement before bursting out laughing, a few of whom became good friends, good clients, or both.
Robots need type too.
