programming language with Lego products. Until 1989, Lego minifigures only came in yellow-skin color with a standard smiling face, though early prototypes had a variety of skin colours and facial expressions. That year the Lego Group expanded the array of facial expressions (adding them around the standard face of two eyes and smile), with beards and eye patches, sunglasses, lipstick, and eyelashes, mostly for the minifigures in the newly launched Lego Pirates theme, and occasionally Lego Castle, Lego City, and Lego Space. Some older collectors resented the new facial expressions, saying they looked too "cartoon-ish" or "kiddy," and preferred the simplistic nature of the two eyes and smile. Particularly for Lego Pirates, these more complicated faces, in combination with the torso, headgear (either a helmet or hair), and accessories, allowed for the creation of specific characters and an accompanying backstory. In 1990, Lego released a new series designed for advanced builders. Three Model Team sets, including a race car and an off-road vehicle, featured a level of detail and realism not previously seen in any Lego series. Where Technic was mechanically accurate, Model Team was visually and stylistically accurate. The Lego Group became one of the top 10 toy companies that year; it was the only toy company in Europe to be among the top 10. Also, that year, Legoland Billund reached more than one million visitors for the first time in its history. The first-ever "Lego Professor of Business Dynamics," Xavier Gilbert, was appointed to an endowed chair at the International Institute for Management Development in Lausanne, Switzerland. Lego Malaysia was also established in 1990. In 1991, the Lego Group standardized its electrical components and systems; the Trains and Technic motors were made 9V to bring the systems into line with the rest of the Lego range. In 1992, two Guinness records were set using Lego products: A castle made from 400,000 Lego bricks, and measuring 4.45 meters by 5.22 meters, was built on Swedish television, and a 545 meters long Lego railway line with three locomotives was constructed. Duplo was augmented with the addition of the Toolo line featuring a screwdriver, wrench, nuts, and bolts; the Paradisa line, targeted towards girls, brought a variety of new pastel colours into the Lego system and focused on leisure resorts, horses and beach life. In 1993 a Duplo train and a parrot-shaped "brickvac" that could scoop Lego pieces up off the
