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?
A Q&A with Figma's VP of Product
Since we launched FigJam back in April, teams having been using it to grow all kinds of ideas into great designs. We recently caught up with Figma's VP of Product, Yuhki Yamashita, to hear what it was like to build FigJam and how things have changed since then. Here, he reflects on the evolving role of design and product management, what it means to welcome “non-designers” into the process, and the future of FigJam.
Stretching the product
When we’re thinking about where to take our product next, we actually take a lot of inspiration from our customers and the Figma Community, to see how they’re stretching our product in interesting or unexpected ways. We saw this happening in the early days of the pandemic. Our users were starting to use Figma for everything from brainstorming ideas to running team warm-up activities, to even putting on social events for people to get to know each other. We saw a lot of use cases that got us thinking.
Engineering, design, and product management
The boundary between engineering, design, and product management is blurring. Some of us used to have a mental model in which roles and responsibilities dictated how things work—that designers do one thing and engineers do another, for example. Increasingly, more people are crossing team lines to problem solve together...Now, it’s not about who “owns” what—it’s more of a collective endeavor. And the roles have become more interlocked, and I think that’s fundamentally a good thing.
Embracing the mess
Design is non-linear. At Figma, we often talk about “embracing the mess,” and that really means leaning into the chaos and complexity that makes the design process what it is. Even once you have the seedling of an idea, you need to explore and iterate, then pull back and evaluate to see what’s working and what’s not. Sometimes you’ll scrap an idea after a brainstorm session, and other times you’ll get pretty far with a concept, but still need different perspectives and input to move forward.
