a dashboard with moving gauges and charts of previous values. They can
migrate towards solving "real problems" and producing useful software
in a series of tractable steps. They can develop the confidence to
leave the simple interactive turtle graphics environment and produce
other kinds of software, such as command-line tools, network daemons,
and Web applications, without needing to overcome any fundamental
hurdles.

To get started, install Chicken Scheme from your package manager, as
well as the SDL and Cairo libraries. You might also need to install
additional the SDL_gfx library if it isn't bundled with SDL on your
platform.

Then install simple-graphics with the following command:

<pre>chicken-install -s simple-graphics</pre>

If you get any errors about linkage problems, you might not have all
of the required bits of SDL and Cairo installed; generally, a Google
search for the error message you get and the name of your operating
system will help!

Finally, when the install is complete, you can start drawing pictures
with the following commands:

<pre>csi
(use simple-graphics)
(forward 5)</pre>
