Piet Mondrian, a Dutch painter famous for using straight lines and simple bright colors.
A grid of little yellow squares like city lights, dotted with red and blue, buzzing across a white background.
Mondrian painted it in 1942 in New York, inspired by the city's busy streets and a lively music called boogie-woogie.
Instead of solid black lines like his earlier work, he made the lines out of tiny colored blocks that seem to blink.
Follow the yellow lines and they feel like cars and taxis zipping along the streets of a bright, busy city map.
You can see it at the Museum of Modern Art, known as MoMA, in New York City in the United States.
Mondrian loved to dance, and you can almost feel the rhythm of the music jumping through this cheerful painting.
