Caustic (optics)
Caustics made by the surface of water.
In optics, a caustic is the envelope of light rays reflected or refracted by a curved surface or object, or the projection of that envelope of rays on another surface. The caustic is a curve or surface to which each of the light rays is tangent, defining a boundary of an envelope of rays as a curve of concentrated light.
Hiding Images in Plain Sight
An Article by Matt FerraroI recently made a physical object that defies all intuition. It's a square of acrylic, smooth on both sides, totally transparent. A tiny window.
But it has the magic property that if you shine a flashlight on it, it forms an image.

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.
Architectural Caustics
A Research PaperTo control the shape of a caustic pattern generated by a specular or refractive surface, we need to solve the inverse problem: how can we change the surface geometry, such that incident light is redirected to produce a desired caustic image?
Design Discourse is in a State of Arrested Development
[Designer News] is good, useful content, but most of it is written by designers themselves. Taken as a whole, it’s also a useful illustration of something vital that our industry lacks: balanced, insightful, independent writing that critically evaluates the profession.
Starved for good journalism and criticism
Imagine for a moment if Kimmelman–or any architecture critic–was also a practicing architect, building enormous commissions for corporations at the same time he writes his columns. If this were the case, you’d probably come to one of two conclusions: either the writer in question was not a serious critic, or that the art form itself is not very serious. You might also stop to think how much poorer we would be without the contributions of his independent voice to the discussion of the craft.
That is exactly the situation that the design profession finds itself in today. We are lucky to have designers actively sharing knowledge, but we’re starved for good journalism and criticism.
The allure of clicks
If more of us, as designers, approach what we encounter on design aggregators every day in this way, perhaps we can begin to effect some structural change. By and large these sites are just as susceptible to the allure of clicks as the craft of design. But if we are more selective about what we consume, we may be able to encourage design publications to follow that lead by applying editorial judgment to what gets shared every day.
