As far as I can gather, that module doesn't support traditional (non-lisp) syntax, along the lines of traditional logo graphics? Which could be why the tutorial section[1] prefers the (apparently more well documented) "#lang slideshow", which gives some of the same benefits (a simple syntax for graphics) with some of the same [ed: drawbacks] (an IMNHO
slightly higher bar for entry, due to being Scheme, rather than an even easier language).

[ed: Ie: one can't simply cut'n'paste from: http://el.media.mit.edu/logo-foundation/what_is_logo/logo_pr... and get pretty pictures, one has to manually compile (or transpile if you will) from Logo to Scheme first. Which is obviously a job for a computer, not for a brain.]
