When Choudhury was in prison during 1952-54, he wrote his symbolic drama, "Kabar" (The Grave). This was a translation of Irwin Shaw's drama "Bury the Dead". After release from prison, he continued to write "Roktakto Prantor" (1959; a play about the Third Battle of Panipat), "Chithi" (1966) and "Polashi Barrack O Onyanno" (1969). In 1965, Choudhury redesigned the keyboard of the Bangla typewriter. This typewriter was named after him as "Munier Optima Keyboard". It was designed in collaboration with Remington typewriters of the then East Germany.
