Green screen looks terrible sometimes. Here's why. Tom Scott explains.
The first moving walkway debuted at the World's Columbian Exposition of 1893, in Chicago, Illinois and was designed by architect Joseph Lyman Silsbee. 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 ten kilometers per hour (six miles per hour).
