When Pam Cronrath's husband Bill died last year, after nearly 60 years of marriage, she knew what she wanted to do, but not exactly how.

"I promised him a super wake," she told the BBC.

What she didn't expect was that keeping the promise would lead her into the world of holograms, technology more commonly associated with celebrities than memorial services in rural America.

Pam, 78, lives in Wenatchee, Washington, an agricultural community on the eastern edge of the Cascade Mountains.

A self-confessed tech enthusiast, she says her outlook was shaped by a career that stretched back to the early days of the internet.
