Here are the sources of the icons used for lbproject.

Non-sketch icons:

The W3 validator icon (to be used on our web pages and not the brochure) has
been downloaded using wget http://www.w3.org/Icons/valid-html40.png.

Sketch-based icons:

Most (in fact all, at the moment) sketch-based icons include a vectorized tux.

Original source for colour vector-based Tuxen is the work of Larry Ewing
(artistic inspiration), Simon Budig, and Anja Gerwinski (see
http://www.home.unix-ag.org/simon/penguin).  Much thanks to all!  

The results obtained here are derived from results in
http://www.home.unix-ag.org/simon/penguin/penguin-2.0.tar.gz.  When
penguin-variant.sk is run through the sketch programme and output as
(encapsulated) postscript, the result is a little more complicated (shadow
near feet) than the Tuxen displayed at
http://www.home.unix-ag.org/simon/penguin/. This foot shadow creates an
asymmetric boundary for the result which is not particularly suitable for
icons.  With the sketch programme (a wonderful LGPLed vector graphics
tool!), I removed that shadow object 
==> penguin-icon.sk.  

For the watermark results, I needed a simpler image, and penguin-flat from
the above source was ideal.  For some reason I could not get penguin-flat.sk
to run from the above tarball so I used the eps result as the source
instead: 

pstoedit -f sk: penguin-flat.eps penguin-flat-origin.sk 

then used sketch to move the origin to 0,0 and output results
==> penguin-flat-origin.sk

With sketch I also colorized this image with 93 per cent white (useful
for watermarks)

==> penguin-whitewashed.sk.

An earlier version of this in CVS was based on a 90 per cent white
colorization of penguin-icon, but that image was too complicated (leading
to long printing times) just for a watermark so that is why we have moved
to penguin-flat-origin as the source of the watermark images.  A commented-out
stanza in ../Makefile also uses penguin-flat-origin for the first-page icon,
but that looked too crude and garish so we have decided to stick with
penguin-icon for that icon.

penguin-whitewashed.sk now has two rotated variations (since rotations much
easier to deal with in sketch than in latex).  left_whitewashed.sk is
rotated counter-clockwise by 50 deg and adjusted in size and displacement so
that the paper outline would just cut it off as is wanted in the brochure
watermark.  right_whitewashed.sk is adjusted similarly for a clockwise
rotation of 180+50 deg.

canadian-tux.sk is based on penguin-icon.sk with a layer to change the chest
to white (to remove markings that interfere with the maple-leaf) and another
maple-leaf layer for the chest area.  Note only a small amount of sketch work
is required to replace the maple leaf by any other institution's logo.  (But
if you do such a thing, name the resulting file something else.)

applications-ca-tux.sk and distributions-ca-tux.sk are used for the VLUG
brochure to head the corresponding sections of the brochure. These are all
based on canadian-tux.sk with a special written headline that tux is
"thinking" (a la cartoon style) for each section. applications-tux.sk and
distributions-tux.sk are vanilla versions of these (used in the
generic_world brochure) without the white chest protector and maple-leaf.

Deprecated icons:

There was no room to use links-ca-tux.sk (yet another variation on the tux
theme to head the resources section) in the vlug brochure, but we will leave
it for now in case someone else can use it or vary it.

Removed icons:

N.B. Only the sketch source files are put under cvs control. The eps results
are generated by each user under Makefile control using the sk2ps
command-line python script that is part of the sketch package.  In the past,
we have had eps icons under cvs control but those (penguin-flat-origin.eps,
penguin-icon.eps, and penguin-whitewashed.eps) have now been deleted from
cvs.

The Monochrome Tux logo was downloaded from Larry Ewing's penguin page at
http://www.isc.tamu.edu/~lewing/linux/penguin.eps.gz and uncompressed. It is
no longer used (didn't like no colour and no source) and was eventually
deleted from cvs.

The Colour Tux log was downloaded from Larry Ewing's penguin page at
http://www.isc.tamu.edu/~lewing/linux/sit3-shine.7.gif. It is no longer used
(gif's are bit-mapped so not scalable) and was eventually deleted from
cvs.

The original Victoria LUG logo was downloaded from
http://ladybug.vlug.org/images/vlug_big.gif.  This was used in the example
(from VLUG) membership application form, but has now been superseded by
the sketch-based, vlug.sk.  Thus, vlug_big.gif has now been deleted from
cvs.
