Mosaic was a subtheme of the LEGO Basic theme, which began in the 1970s, was designed to be a more general, non-thematic series of sets. Unlike the themed sets that revolve around specific stories, characters, or concepts (e.g., space, city, or pirates), the Basic theme provided a collection of standard LEGO bricks and pieces, often in a variety of colors. The goal was to encourage free building and creativity without the confines of a specific theme or narrative.
2000 LEGO Sets
2000 was a year of transition and innovation for LEGO. The company introduced RoboRiders, Knights’ Kingdom, Life on Mars, Studios, and a Soccer/Football theme while retiring veteran designer Jens Nygaard Knudsen, creator of the minifigure. Star Wars launched its first Ultimate Collector Series sets—the X-wing Fighter (7191) and TIE Interceptor (7181)—establishing LEGO’s adult collector market. BIONICLE debuted in select regions, setting the stage for a major global launch. Recognized as 'Toy of the Century,' the LEGO brick entered the new millennium as both a cultural icon and a growing creative platform.
