Hi all..

1. I'm learning Smalltalk (since yesterday) using Squeak and I notice that
there is some VRML related stuff in the library.  Where can I find
documentation for those VRML objects, especially some example code showing
how to use them?

2. The Swiki site has loads of customisation pictures, but no descriptions
of how to do that customisation.  For example, how do I change my
environment background (or any other window for that matter) to an image
instead of garish green?

3. To run Siren, do I need to use the older VM or can I just use Squeak
version 2.6 with the image on the Siren site, which I believe was made with
about version 2.4?

4. How do I execute an external program and get stdout output from that
program back into Squeak?  (I would like to turn a bunch of data from an
external program into VRML and/or a 3D display.)

5. Is there documentation for the 3d library?

6. Is it possible to produce a standalone deliverable application with all
unnecessary stuff removed, using Squeak?  (not a major issue, I'm just
curious).

7. If you customise your working environment, is that lost when you load the
latest set of updates to Squeak from the internet?

I look forward to your responses.

Mike Thomas.
