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.

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.
To 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?
PEOPLE ARE NOT THEIR JOB TITLES.
TEAM MEMBERS ARE NOT “RESOURCES”.
PEOPLE WORK BEST WHEN THEY CAN BE THEIR FULL SELVES.
YOU CANNOT CALCULATE AN ROI FOR DESIGN.
FRAMING THE PROBLEM IS MORE IMPORTANT THAN SOLVING THE PROBLEM.
(DESIGN) LEADERSHIP IS MORE TALKING THAN DOING.
YOU’LL DO A BETTER JOB IF YOU LIGHTEN UP
IF YOU HAVEN’T PISSED SOMEONE OFF, YOU’RE NOT DOING YOUR JOB RIGHT.
NO ONE OUTSIDE YOUR TEAM UNDERSTANDS WHAT IT TAKES TO DO GOOD WORK.
THE OUTCOMES ARE BETTER WHEN EVERYONE IS A DESIGNER.
AGILE TRANSFORMATIONS ARE HOSTILE TO GOOD DESIGN.
WHAT A DESIGN TEAM NEEDS MOST IS A CLEAR SENSE OF PURPOSE.
YOU ARE ON THE FRONT LINE OF A GLOBAL WAR FOR TALENT.
EVERYONE APPLYING FOR A ROLE HAS AN INFLATED TITLE.
INTERVIEWS ARE A POOR WAY OF ASSESSING CANDIDATES.
DESIGN EXERCISES ARE A BAD INTERVIEWING PRACTICE.
YOU WILL NEVER HAVE ENOUGH DESIGNERS.
YOU WILL NEVER HAVE ENOUGH TIME.
THE SKILLS THAT GOT YOU HERE ARE NOT THE SKILLS THAT WILL CARRY YOU FORWARD.
