I will give it a go. I love this style of art. It is so steampunk looking.

STEAMPUNK
An amalgam of science fiction, high camp, and speculative
history. The game is afoot, Sherlock, in tracking down the
story behind this relatively new word. Imagine, if you
will, a word and genre built like the time travel machine
in the H. G. Wells novel, made up of bits and pieces of
every gizmo known to the late 19th century. Steampunk
resembles that machine, but in a retro sense, cobbling
together such genres as “science fiction, alternate history,
and speculative fiction that came into prominence during
the 1980s and early 1990s.” One of the hallmarks of steam-
punk is nostalgia. It is redolent of Victorian locations and
an era when steam power still held sway, and it celebrates
other forms of “anachronistic technology,” such as dirigi-
bles or mechanical computers or futuristic innovations, at
least as Victorians such as Wells and Verne may have envi-
sioned them. The steampunk sensibility can be enshrined
in the following anecdote: “When Professor John Henry
Pepper was demonstrating certain pieces of chemistry
[equipment] before an audience that happened to include
Queen Victoria, he is reported to have calmly introduced
one demonstration with: ‘The oxygen and hydrogen will
now have the honor of combining before Your Majesty.’ ”
Companion words include K. W. Jeter’s gonzo-historical,
and cyberpunk.

I am curious...what are the proper dimensions for GC banner?

Very cool, Rod!
