It never occurred to me how perfect programming languages are for poetry. You have all these extra characters and whitespace to change how a piece of text feels or reads, and it becomes a visual experience too, like looking at art. Are there other program-poems people should look at? The only thing I'd seen like this before was "Sunrise, Sunset" written in PHP. I know these things aren't new for many of you but I keep being surprised by the creativity I find.
