There’s an interesting [review of _10 PRINT CHR$(205.5+RND(1)); : GOTO 10_ at Slate][slate]. For those that don’t, like me, recognize that particular line of code, it’s from a Commodore 64 program that would create an ever-incrementing maze on the screen. The [book about the line of code][book] seems to be wide ranging and playful and thus, to my mind, worth a look. By the way, the book is available through a Creative Commons license and can be purchased in codex form in support of two nonprofits or downloaded for free as a PDF. My advice? Check out the PDF and if you like the book, buy the codex.
