About
There are hidden memorials to the dead in the internet's overhead! Inspired by the story of the Clacks in Terry Pratchett's Discworld series, developer use the "x-clacks-overhead" header to pay homage to those who have departed. "Keeping their name forever alive. As long as their name is still passed along the Clacks, Death cannot have them."
