The evolution of form begins with the perception of failure, but it is propagated through the language of comparatives. "Lighter", "thinner," and "cheaper" are comparative assertions of improvement, and the possibility of attaching such claims to a new product directly influences the evolution of its form. Competition is by its very nature a struggle for superiority, and thus superlative claims of "lightest," "thinnest," "cheapest" often become the ultimate goals. But the goals more often than not are incompatible. Thus, the lightest and thinnest crystal can be expected also to be the most expensive. But limits on the form of artifacts are also defined by failure, for too light and too thin a piece of crystal might hardly be usable.
We realized a few years ago that the value of switching to Slack was so obvious and the advantages so overwhelming that every business would be using Slack, or “something just like it,” within the decade. It’s validating to see you’ve come around to the same way of thinking. And even though — being honest here — it’s a little scary, we know it will bring a better future forward faster.
However, all this is harder than it looks. So, as you set out to build “something just like it,” we want to give you some friendly advice.

New milling techniques applied to glass and plexiglass panels could be used to “create windows that are also cryptic projectors, summoning ghostly images from sunlight.”
[Pauly and Bompas] hope that the technique will be used in architectural design, to create windows that mould sunlight and throw images or patterns onto walls or floors,” which, if timed, milled, and manipulated just right, could produce a slowly animated sequence of images being projected by an otherwise empty window during different times of day.
