send a "vis" message to Pd¹.
the vis message takes the base path to your Pd(-GUI) installation.

since this can be different for each system, you can use something like 
this to dynamically get the right path:

```
[symbol ../tcl/pd-gui.tcl(
|
[file which]
|
[symbol $1/../..(
|
[file normalize]
|
[vis $1(
|
[s pd]
```

if you provide no argument (e.g. [; pd vis(), the GUI will be closed.

(i think the interface is a bit ugly, and we should be able to simply do 
[; pd vis 1(, resp [; pd vis 0(; but that's just syntactic sugar)

¹ you have to provide your own means to send that message to Pd, once it 
is running headless. Pd provides plenty of ways to do that.
