A moving walkway (British English) or moving sidewalk (American English) (colloquially sometimes travelator, horizontal escalator, walkalator, autowalk, movator, people mover) is a slow moving conveyor mechanism that transports people, across a horizontal or inclined plane, over a short to medium distance. Moving walkways can be used by standing or walking on them. They are often installed in pairs, one for each direction.

The first moving walkway debuted at the World's Columbian Exposition of 1893, in Chicago, Illinois. It had two different divisions: one where passengers were seated, and one where riders could stand or walk. It ran in a loop down the length of a lakefront pier to a casino. Six years later a moving walkway was also presented to the public at the Paris Exposition Universelle in 1900. The walkway consisted of three elevated platforms, the first was stationary, the second moved at a moderate speed, and the third at about six miles an hour. These demonstrations likely served as inspiration for some of H. G. Wells' settings mentioned in the "Science Fiction" section below.

Keller Williams (born February 4, 1970) is an American musician from Fredericksburg, Virginia, who began performing in the early 1990s. He is also known by the names K-Dub or just Keller, when performing. Williams' music combines elements of bluegrass, folk, alternative rock, reggae, electronica/dance, jazz, funk, and other assorted genres. He is often described as a 'one-man jam-band' due to his frequent use of live phrase looping with multiple instruments.

Though primarily a solo artist, Williams has toured with several bands that include Yonder Mountain String Band, The String Cheese Incident, Umphrey's McGee and Ratdog, and has frequently performed at The Bonnaroo Music and Arts Festival, the AllGood Music Festival, Summer Camp Music Festival, and the The Rothbury Festival. Williams has an audio taping policy of his performances, and for non-commercial trading of the recordings but use of video or flash photography, or any recordings for profit are prohibited.

Keller Williams Incident is a collaborative performance between Williams and The String Cheese Incident. They have performed together, and Williams' 1999 album Breathe was released collaboratively as the Keller Williams Incident. Williams and SCI began collaborating after Williams saw the band perform in Colorado; offering to play with the band in exchange for free ski passes.
