For games, there are a lot of things you could possibly want to
delegate to scheme, while pushing lots of pixels. For example, you
could write one of those 3d first person games, with levels stored as
scheme files and the enemy ai written in scheme. Another example is a
game like abuse, where pretty much all of the game is written in a
lisp-like language.

For serious apps, using guile for 'active content' (buzzword alert!)
on the web is probably the most likely candidate, though you could add
in a word processor that just isn't complete without a few animated
pictures to convince the user something exciting is going on. A
modeller with scheme as an extension language would also want this
sort of thing if it provides a way of creating and viewing
animations.
