History,

The designers' (Pierre Smith <pierres@switchdesign.com>) have provided
a Logo and Text, this can be seen as the bottom of the 4 logos.  This
was provided as an EPS file and converted to SVG by Paul Sladen.

In the meantime (during the Oxford conference) Paul Sladen also drew
from scratch a copy of the logo which is symmetrical and used the
colours provided on the designer's colour swatch.  This can be seen as
the second from bottom.

After importing and comparing these, the colours are slightly
different; The designers' have provided named CMYK Pantone colours for
printing but not RGB on-screen equivalents.  (See "designers-swatch.jpg").

Somebody needs to pick which of the logos looks the better and which
of the (slightly different) colour sets look the better.
