In 1991, the year that Glen Hansard started The Frames, he also played Outspan, the baby-faced Dublin guitar player in "The Commitments, " a feature that has gained a global following. (It's one of my favorite films ever.) What makes "The Commitments" so widely loved is, among other pleasures, its use of a working-class rock band's rise and fall as an armature for individual drama.
One intriguing notion that has occurred to me after considering the design of Glass is that with this band that wraps around the head, Google is creating a standardized armature from which to hang a range of augmentations.
