I have a habit of installing quirky screensavers on my Macs as a throwback to an earlier era. But with my latest Macbook Air I fell in line with the default settings sans screensaver, dissatisfied with what was out there. That all changed when I saw this screensaver by designer Robert Padbury, developed by Steve Streza. It’s a twist on the iOS7 lock screen with options for white on black or black on white typography. It’s minimal and extremely elegant.
