Travel back to 2009 when Flash, Flex and Adobe AIR were still hip and popular technologies.
This ancient project from 2009 was a proof of concept application that showcased a possible solution to share and review site designs with other people.
It used a Flex AIR application connected to a PHP backend.
Work was stopped when Adobe introduced similar functionality into its software.
And of course, today we know choosing Adobe AIR was not a future-proof choice.
