It is fun to revisit memories this way, a digital stamp in my weather passport, where everything can be contained in a forecast and Stockholm sits between Vilnius and London by sheer chance. It has also been a way to feel close to people I love while traveling, to know whether it is raining where they are.
As with most technology, this is artistry by committee. There is no Thomas Cole waiting in the wings. But someone has to animate the stars, to decide when to streak one across the screen–to play god in our pockets.
Brian Eno is well-represented in iOS. His other apps like Bloom, Trope and Air invite listeners to touch the screen to make their own composition. Reflection ($30.99) is different, there is no interaction for the listener. The interface has three buttons: a pause button, a sleep timer, and AirPlay. Reflection produces endless permutations of Eno’s 2017 album, an hour and five minute long title track.
“Just calling it an app is akin to saying Falling Water is just a building,” writes one app store reviewer. “I would not call this an app,” agrees another, “Between the music and visuals it’s more like sonic architecture.” The visuals consist of slowly morphing rectangles that only seem to change in the split second you look away from the screen.
These days I am more interested in the reverse case [of Da Vinci's helicopter]: ideas that could have worked many centuries before they actually appeared. The economist Alex Tabarrok calls these “ideas behind their time”
Curious minds want to know why these ideas appeared so late — and whether there might be anything that would prevent delays in future. One explanation is that the ideas aren’t as simple as they appear.
The bicycle is not as straightforward an invention as it seems. To move from ox-hauled cart to human-powered bicycle requires smooth-rolling wheel bearings, which in turn need precisely engineered bearing balls. Modern steel ball bearings were not patented until the late 1700s, and demand from the 19th-century bicycle industry helped to improve their design.
