Pursuing a figure that resembles a capital Greek 'pi' (two vaguely
Y-shape verticals joined at top), I am led to identify this mark as a
cunieform 'min' figure, meaning 'two' and reflecting a dual nature
akin to what Aspies manage in a world that is not theirs. The Y
shape is formed by a reed writing tool pressed into clay tablets
by Sumerians, as I recall from a long-ago humanities class, an
attempt to drum a sense of culture and history into the heads of
adolescents in the 1960s. Not much stuck, I fear. Alas. -Zer

http://www.aspergia.co.uk ~ Aspergia and Asperger's. A new way
of thinking... The Dual Thread. Representing the combination of
both Aspergian and non-AM [see below] traits, the Aspergian
logo reflects the duality of Aspergian existence by using the
cuneiform symbol for "min" (two). Aspergians also reflect this
symbolism by signing their name with the Dual Thread next to it.
==> AM ~ Aspergian Mutation, a term used by Aspergians to
replace the terms "Asperger's Syndrome" or "High Functioning
Autism", both of which perpetuate the perception of Aspergians
as suffering from a "condition".

http://members.ozemail.com.au/~ancientpersia/language.html is
a fascinating read, including this info.==> Cunieform was written
on wet clay tablets using a long reed or 'stylus'. Its name is
derived from two Latin words meaning "wedge-shaped".
