Amusement parks have been growing rapidly in Indonesia in the past five years but they seem affordable only for the middle and higher classes of society. Surabaya in East Java has several amusement parks that cater for low budgets and they have good-quality equipment and are safe to use. The purpose of this research is to show the results of building a low-cost amusement park. The amusement park was built by a player in the amusement park industry in collaboration with the Computer Engineering Department of Bina Nusantara University. An infinity mirror room (IMR) was built in one of the new amusement parks in Surabaya called Suroboyo Night Carnival. The full design of the IMR is discussed in this paper including the equipment used in the design. The IMR mainly uses fibre optics, LED and a mirror. The amusement park began operation on July 28, 2013, and the amount spent on one room was around US$8,500. No safety breaches have been reported. The facility has been able to attract 500 visitors on average from 2013 to 2016. The breakeven point of this facility was achieved in the first year of operation.
