Which is why I thought a two-armed spiral, based on a real galaxy,
would be appropriate. Clearly different from Debian's spiral, anyway.

The Milky Way indeed seems to have two main arms, with two vestigial
arms between them. But there is a dearth of photos of the Milky Way
that clearly shows the spiral arms, and this is likely to continue for
at least myriads of years.

There is a public-domain drawing of the Milky Way, but it presents
the Milky Way as a barred galaxy, and the par seems to have been kind
of air-brushed onto the image rather than integral to the staarfield.

And a schematic diagram of the arms, which appears to be under the Gnu
Free Documentation license:

I'd like to see the first of these worked up into a simple but
interesting logo image. Something that's effective in only two colors
(such as black and white, or any other foreground-background pair) and
still has some - but not all - of the complexity of reality.
