I've written an interactive turtle graphics package, complete with animated turtle imagery, aimed at Dr Racket using parents with elementary-school aged kids.
It's available on github: https://github.com/danprager/turtlegraphics Online docs and tutorial<http://htmlpreview.github.com/?https://github.com/danprager/turtlegraphics/blob/master/turtle-graphics.html> . I'd appreciate tips in a couple of areas: 1. Code organization: At the moment everything is dumped in one directory. My problem is that when I put -- for example -- an example in an /examples subdirectory and (require "../turtle-graphics.rkt") the line (define *turtle-image* (read-bitmap "turtle.png")) in turtle-graphics.rkt treats the subdirectory as the current directory rather than the parent directory, giving a file not found directory. 2. How do I turn an image built up from (empty-scene ...) into a bitmap% ? I want to use (write-animated-gif ...) to make a few animated gifs to spruce up my documentation. Finally, is this the kind of thing that would be worth putting up on PLaneT straight-away, or better to mature it a bit on github? Thanks Dan
