Anyone have any idea what is the origin of the Sahara features?

Do you believe in astrology? Jupiter exerts less gravitational influence
over a human body than an angry rhino less than two meters away...

Bob Clark:
Star dunes are formed when strong winds
blow from several different directions.
I.e., no prevailing wind direction is experienced in the area,
but there are some recurrent wind directions.

Now, in your subject line:
David Jones remade himself into Ziggy Stardust,
possibly inspired to do so by Martian spiders, so check out
the earlier part of the body of work of David Bowie.
