Dominoes are small, flat blocks used as gaming objects. They are usually made of wood, but may be plastic, bone, or other rigid material. Most dominoes are marked with a number of dots (or “pips”) on each end. Larger sets are often marked with Arabic numerals. Most domino games involve stacking the pieces on their edges in long lines, then knocking them over one at a time. When a domino is tipped over, it triggers the next piece in line to tip over, and so on, until the entire stack has fallen. Some people also use dominoes to create art, such as curved lines or grids that form pictures when they fall.

Lily Hevesh started playing with dominoes when she was 9 years old, using a set her grandparents had. She loved setting them up in straight or curved lines and flicking the first one to watch it fall. It didn’t take long for her to start posting videos on YouTube of her amazing domino setups. Now, at 20, she is a professional domino artist who creates stunning setups for movies, TV shows, and events—including the album launch for Katy Perry.

She creates her mind-blowing domino setups by following a version of the engineering-design process. She starts by considering the theme or purpose of the installation and brainstorming images or words that might be associated with it. Then, she plans out the design and calculates how many dominoes are needed to achieve it. Once the design is finished, she tests it to make sure it will work.

In the past, domino has been used as a symbol of power, and it continues to hold this symbolic meaning today. It is also a popular word for a type of game that can be played with just a few pieces, but can have huge consequences if the first player gets it wrong. The word domino comes from the Latin for “fall.”

As Domino’s grew, Monaghan focused on opening locations near college campuses to cater to students. This was an important strategy that drove the company’s growth until it reached 200 locations by 1978.

In the early 1960s, President Dwight Eisenhower used the term “domino theory” to describe the ability of a single leader to inspire non-communist forces in Southeast Asia to fight off Communist insurgents. This doctrine was an important component of the U.S. commitment to support the Ngo Dinh Diem government in South Vietnam and in Laos. In later years, the U.S. would increase its military support for these forces in an effort to contain communism in Southeast Asia.
