Code poetry

Code poetry is literature that intermixes notions of classical poetry and computer code. Unlike digital poetry, which prominently uses physical computers, code poems may or may not run through executable binaries. A code poem may be interactive or static, digital or analog. Code poems can be performed by computers or humans through spoken word and written text.

Examples of code poetry include: poems written in a programming language, but human readable as poetry; computer code expressed poetically, that is, playful with sound, terseness, or beauty.
