[plt-scheme] Demo of a graphics library for scheme

I have been fooling around with binding a graphics library written in C
to mzscheme and would like to present what I have so far. There are a
few examples in the package that show usage of graphics, keyboard input,
mouse input, and sound. It should work on most unix's and Windows but
not OSX( yet ).

First download the scheme code:
http://www.rafkind.com/jon/tar/allegro-scheme-0.2.tar.gz

examples are in the
allegro-scheme-0.2/{examples,examples/piano,examples/xquest} directories

If you are on windows download the Allegro dll and put it in
c:\windows\system32\
http://www.rafkind.com/jon/tar/alleg42.dll

If you are on *nix download the Allegro source and a shell script I
wrote to automatically build and install it:

http://prdownloads.sourceforge.net/alleg/allegro-4.2.0.tar.gz?download
http://www.rafkind.com/jon/tar/make-allegro.sh

$ ./make-allegro.sh allegro-4.2.0.tar.gz

I would really like for everything to Just Work( tm ) so if anything
breaks let me know. Im also interested to know if people find this whole
thing interesting to begin with.
