Did You Know that the Computer Graphics Revolution Began in Utah?

David Evans and Ivan Sutherland from the University of Utah used their math, physics and electrical engineering skills to revolutionize computer graphic imaging technology.

Real or unreal? This is one of the latest Evans and Sutherland projects—a curved 8K, 20-meter dome immersive experience. According to InPark Magazine: Evans & Sutherland, Spitz, and LiveLike VR join immersive forces as Cosm to build these displays for science, education, theme parks and sports. (Yes, this is a screen).

Two men who stand out as the foremost Tech Pioneers in Utah are without a doubt David Evans and Ivan Sutherland.

This dynamic duo used their math, physics and electrical engineering skills to revolutionize computer graphic imaging technology. They literally built the first computer graphics simulation engines, and they and their students pioneered the field of CGI (Computer Graphics Imagery). Out of their labs came Adobe, Pixar, Atari, Xerox, and PARC, a subsidiary of Xerox, which invented the first GUI (graphical user interface, and which Apple copied and built into the Macintosh), and a host of graphic simulation engines used by the U.S. Military.

How did this happen in the sixties, when Utah was just a small blip on the tech pioneer map?

In 1965, the University of Utah recruited Evans to establish a state of the art computer science program. In 1968, he convinced his friend from Berkeley, Ivan Sutherland, to leave his teaching position at Harvard and move to Utah, which he agreed to do under the condition that they would eventually launch a computer graphics company together.

This power collaboration shaped the history of the computer industry and built one of the most influential university computer graphics programs in the country. Students were encouraged to experiment and discover creative solutions based on the theory that computers could be used interactively for a variety of tasks.

Evans and Sutherland envisioned the use of computers as simulators by using graphics technology to replace real objects, aiding in cheaper costs for military and other development projects. The genesis of the Evans and Sutherland Computer Corporation (E&S) started in the barracks on the University of Utah campus with students recruited from the university. E&S made advances in real-time hardware, accelerated 3D computer graphics, and printer languages, and continues today as a major supplier of military and commercial graphics systems.

The creative and inventive atmosphere Evans and Sutherland fostered as professors and employers stimulated some of the most successful minds in the field of computer science. Many of Evans and Sutherland’s students went on to further expand the field including Alan Kay, inventor of Smalltalk language; Ewin Catmull, cofounder of Pixar, and currently President of Walt Disney and Pixar Animation Studios; John Warnock, the founder of Adobe; and Jim Clark, of Silicon Graphics.

In Robert Rivlin’s book, The Algorithmic Image: Graphic Visions of the Computer Age, he says, “Almost every influential person in the modern computer-graphics community either passed through the University of Utah or came into contact with it in some way.”

This three-story 8K screen (the only one of its kind) is located in Utah at Research Park. It’s the showpiece for Cosm, who is building displays similar to this all over the world, including a curved planetarium in Sweden.

What’s Behind the Buzz Around The Salted Roots?

Salted Roots began as simple kitchen experiments and quickly grew into one of Utah’s most talked-about small-batch food brands. Founder Ivy Watrous has been cooking since childhood, blending bold flavors with careful technique. Today, her handcrafted salts and sugars are showing up in farmers markets, home kitchens, and even cocktail menus — each one shaped by personal stories, long hours, and a commitment to doing things the hard way when it matters.

Utah Craft Whiskey: How Barrels and Utah’s Climate Shape Flavor

Utah’s craft whiskey scene is shaped by more than grain, yeast, and time. The state’s dry climate plays an unusually powerful role in how spirits age, intensifying the relationship between whiskey and the barrels that hold it.

Low humidity accelerates evaporation during aging, often claiming 14–18 percent of a barrel’s contents as the “angel’s share.” Unlike more humid regions where alcohol evaporates faster, Utah barrels tend to lose more water, concentrating flavor and driving proof upward over time. That accelerated interaction pulls sugars, tannins, and spice from the wood more quickly, creating whiskeys that often taste older and more structured than their age statements suggest.

To understand how Utah distillers are deliberately harnessing climate, char, and finishing barrels to shape flavor, two producers at the forefront of that experimentation — Sugar House Distillery and Spirits of the Wasatch — shared how barrel choices influence everything from sweetness and spice to texture and proof.
