I didn't know such a version existed, much less where to look for it.

There are similarities in the shape that has been rolled up to form
the spiral.  The spiral itself differs, though.  The Greek spiral has
about 2.5 revolutions, while the Debial logo has barely 2.  Maybe they
used the same Adobe Illustrator brush that was used to create the
Debian logo, and applied it to a spiral with different parameters.

If you create a logo by using stock items from a widely used graphics
design program, you can only expect to find others using similar
