Sony UX50 New Year's Easter Egg

Gareth Branwyn points us to this post by Nate on streettech.com:

Crazy little January 1st Easter egg appeared on my UX50 (thanks to a heads-up from mattyy at ClieSource): a little fiddling
with the time and a soft-reset caused this man to appear in the
Settings screen for a fleeting moment, holding what appears to be a
driver's license or some sort of ID. Who is this guy? Street Tech swag
to the first person to positively identify this man and post info in
this blog item's Comments area.
