Spotted in Longmont, Colorado, March 2025. Interesting to see that USPS screens are simply a VLC player loop. Interesting details on the screen:

• It's "Restricted information" to see the backend.
• Video build is versioned and deployed by "Technology Applications"... which turns out is a department in the USPS (https://about.usps.com/who/leadership/officers/tech-applications-vp.htm)
• This was up for a few days, so I'm guessing either the staff don't care, or don't have access to troubleshoot.
