I've done some small experiments with a similar library (of my own
devising) and you can do some really neat tricks that are impossible
with bitmap based operations. Rather than trying to copy Python, why
not do something different? For example, if take an image and add
noise you can get some fun effects. Similarly by scaling various
elements. This should be easy with the HtDP representations, but
largely impossible with a pixel based rep. More complex tasks could be
to render a "hand-drawn" version of an image: take the image, break
the components into smaller pieces and add gaussian noise. NodeBox
(http://nodebox.net/ ; in Python) has some nice examples, though their
library is both more powerful and less portable.
