(at the time) theories of physics that postulated that space has up to 11 dimensions; some of these shows featured creative and novel sound tracks composed by composer-in-residence Mychael Danna. While the main attraction continued to be the astronomical shows put on during the day, in the early 1980s, regular laser light shows became a staple evening's entertainment in the city. Typical shows included "Laser Floyd: Dark Side of the Moon", "Laser Zeppelin", "Sgt. Peppers Laser Light Show" and later, such shows of more contemporary musical artists such as "Laser Depeche Mode", "Laser NIN" and "Laser Nirvana". These shows were held under the name "Laserarium" rather than that of the planetarium, though the laser-light and star shows were held in the same building. The laser shows were created by the Florida-based firm Audio Visual Imagineering, whose shows are also seen at other planetaria. Corporate events were promoted through The Planetcorp and included such events as a CTV Fall season launch as well as corporate AGMs of Sun Microsystems and product launches from NEC and other companies. Other exhibits in the revamped Astrocentre included a new 50-seat mini-theatre, wall murals illustrating the phases of the moon, plus an increasing number of hands-on exhibits and interactive computer-driven displays. There were also displays of astronomical globes, an orrery and pictures of the planets, many taken by contemporary space probes. The Astrocentre also featured the world's first commercial Stellarium, a slowly rotating display containing a 3D representation of almost a thousand stars in our immediate stellar neighbourhood. Closure The McLaughlin Planetarium closed on November 5, 1995. The president of the ROM stated that the closure of the planetarium was due to a combination of falling attendance and a declining interest in space, and that the closure was necessitated by provincial budget cuts. The decision came as a surprise to many, as attendance had rebounded in recent years, and the planetarium was one of few in North America at the time that was turning a profit. The closure meant that 40 people lost their jobs. Despite the ROM citing lowered attendance figures, proponents of the planetarium have alleged that the Conservative Ontario provincial government of the time, led by Mike Harris, was looking for an instant and visible $600,000 cut to the ROM's operating budget. No succeeding provincial government has shown an interest in reversing this decision. Shortly after the announcement, the exhibits, seating and
