In web design, a mood board is a collection of features such as fonts, images, icons, and other UI elements that help to define the artistic direction of a project.
Marketers and web designers sometimes use mood boards to pitch creative concepts to their clients and as part of their branding strategy.
The first time I saw one, it actually reminded me of the bulletin boards some people had in their bedrooms in high school and college. This visual presentation is a collage of images, text, and samples of objects based on a topic. Why “mood board”? Because it is used to convey a general idea or feeling about a particular topic. They may be physical or digital.
Mood boards are also used in the creation of videos and films. Digital mood boards are often digital and can include animated gifs and video clips. It can illustrate sets and locations, a color palette, characters, costumes, or almost any aspect of the film. Also known as production design books for film and television, they often are a way of visioning set design, graphic design, or set decoration.
The biggest difference in how mood boards are used is more about who uses them than about the content. A color palette can be used by a set decorator, production designer, web designer, graphic designer, or director.
First came dark matter and dark energy. Now, we find parts of our universe moving at very high speeds and in a uniform direction that can’t be explained by any of the known gravitational forces in the observable universe. Astronomers are calling the phenomenon “dark flow.”
Dark flow is the name given to the motion of galaxy clusters with respect to the cosmic microwave background radiation which should be randomly distributed in all directions. But it is not. A three-year study concluded back in 2008 that there was a common motion of at least 600 km/s toward a 20-degree patch of sky between the constellations of Centaurus and Vela.
This dark flow must be outside the “observable universe.” The “observable” universe doesn’t actually mean as far as we can see with a powerful telescope. There’s a fundamental limit to how much of the universe we could ever observe, no matter how big the telescope.
Vela is a constellation of the southern sky (in the illustration it is at left center) and the word is Latin for the sails of a ship. It was originally part of a larger constellation, the ship Argo Navis. The larger constellation (shown here) was later divided into three parts, the others being Carina and Puppis.
If the universe formed about 13.7 billion years ago, and light started traveling toward us immediately after the Big Bang, the farthest it could ever get is 13.7 billion light-years in distance. So, if there are parts of the universe that are farther away, we can’t see farther than light could travel over the entire age of the universe.
Makes me feel rather small.
One theory to explain this dark flow is that the motion results from the influence of no-longer-visible regions of the universe prior to inflation. Telescopes cannot see events earlier than about 380,000 years after the Big Bang, when the universe became transparent. Another theory is that it is the gravitational influences of other universes.
