Stephen De Gabrielle announced this a few days ago on racket-dev, so I
spent my weekend embracing my inner Star Wars nerd and made
lightsabers in Racket. I had never used the pict library before, so it
was also an interesting learning experience.

Dear Racket friends & teachers,
I’m taking a semester of leave from my teaching position at Kirby School in
Santa Cruz, CA, and the school is looking for a part-time sub to cover my

#lang scribble/base
@(require scribble/core)
@(define (colorize #:color c . content)
(elem #:style (style #f (list (color-property c)))
content))
@colorize[#:color "red"]{WARNING}
But what if you

Here is a map of the world, rendered using a 40 line Racket program and
