1965/1 - ∞, Detail 

Roman Opalka's "1965/1 - ∞, Detail" is a work of Conceptual art. The artwork consists of a series of hand-written numbers, seemingly random, yet the pattern is clearly defined: each number is the next number in the sequence from one to infinity. This work, begun in 1965, was Opalka's lifelong project, and it represents his dedication to documenting the passage of time through this monumental task. As the work continues, the numbers themselves become more significant, as they signify the artist's commitment to the project. The detail image shown here provides a glimpse into the vastness of Opalka's undertaking.
