Apple II (1977) did an early version of this; it essentially had purple and green addressable colors in each pixel. With both on in a single pixel you got white text, but could also leverage two adjacent pixels, one with purple and one with green, to produce a half-pixel offset that could produce a smoother diagonal line than typical fixed coordinates.
This article[1] mentions a composer who "composed primarily for the vibrations and included the music after the initial layout of the haptic composition." We used to put on whatever 3D glasses the theater was providing for big new 3D movies; why not don a vest to listen to Deadmau5?
It's not well-explained in the article but there's a separate artist "playing" the haptic vests via programming, not unlike how a lighting engineer programs the synchronized light shows for a big touring act.
Instead of a DMX controller choosing entire scenes that control banks of lights in unison, or narrowing down to individual banks of lights to fine-tune things on the fly with faders, the haptic vests use similar commands and controllers to program different intensities and patterns of vibrations across the sub-regions within the vest.
The haptic engineer/artist usually has packs of go-to scenes that work well and provide distinct but complimentary effects from each other scene (just like the lighting engineer), and may have an entire effect chain pre-programmed for a song or mix, or may be choosing and mixing the haptic scenes on-the-fly as they listen to the audio.
Safari has done this for a long time when you have multiple tabs with similar titles open.
I think the intent is to increase the unique text within the tab titles when you are reading sites that have titles like "My Blog - Tuesday's Article" and "My Blog - Wednesday's Article"; otherwise these would both shorten to "My Blog - ..." as tab count increases, or as other tab width constraints come in to play.
Granted, the heuristic for identifying common text between tabs isn't always great and can sometimes just result in titles looking cut-off.
The Federal Reserve has a board of seven governors, and twelve regional banks (one in Atlanta). Along with that board, the president of the New York regional bank, and four others on a rotating basis, form the body that votes to set policy.
Apple's iCloud Drive has a decent web interface for the non-Apple subset of "any device", and otherwise seems to offer what you want. Curious if you had other reasons it doesn't meet your needs.
