In the 2000s, Sol LeWitt continued to evolve his exploration of conceptual and minimal art, introducing new forms and expanding on his iconic use of geometric shapes and colors. This period was marked by a significant shift in his artistic approach, with LeWitt delving into more curvilinear shapes and vibrant colors, moving away from the strict geometric vocabulary that had defined much of his earlier work. His late works in the 1990s and early 2000s demonstrated a growing interest in somewhat random curvilinear shapes and highly saturated colors, indicative of a radical departure towards "something not geometrical"​ (Wikipedia)​. One of LeWitt's notable projects from this era was "9 Towers," conceived in 2007 and installed at the Kivik Art Centre in Sweden. This work, made from more than 1,000 light-colored bricks and measuring five meters on each side, showcased LeWitt's enduring fascination with modular structures and his ability to transform simple geometric forms into complex, engaging artworks​ (Wikipedia)​. Throughout his career, LeWitt emphasized the idea behind the artwork as more significant than the artwork itself. This principle led him to delegate the execution of many of his works to others, based on detailed instructions he provided, a practice that continued into the 2000s. This approach facilitated a sort of democratization of art-making, challenging traditional notions of authorship and the role of the artist​ (Art in Context)​. LeWitt's wall drawings remained a significant part of his work during this period, characterized by their large-scale nature and the use of a wide range of materials, including graphite, crayon, colored pencil, and acrylic paint. These works were executed by teams of assistants following LeWitt's instructions, underscoring the conceptual foundation of his art. The process of creating these drawings was seen as a collaborative effort between the artist, the assistants, and even the viewers, who were invited to engage intellectually with the work​ (Wikipedia)​​ (SFMOMA)​. The 2000s marked a period of continued innovation and exploration for Sol LeWitt, as he pushed the boundaries of conceptual and minimal art with new forms, colors, and collaborative processes. His work from this era reflects a playful and experimental approach, yet remains grounded in the conceptual principles that defined his entire career.
