X-Clacks-Overhead

Display the X-Clacks-Overhead in Clacks Semaphore, including http-equiv meta tags. Forked from GNU_Terry_Pratchett

X-Clacks-Overhead is a Chrome extension paying homage to the late Sir Terry Pratchett by displaying the "GNU Terry Pratchett" message embedded in website headers. It detects the X-Clacks-Overhead message either from HTTP headers or http-equiv meta tags, showing it visually in the semaphore style inspired by the Clacks board game by Backspindle Games.

Forked from the original GNU_Terry_Pratchett extension, this improved version fixes header detection issues to reliably display the tribute. Designed by Richard Atha-Nicholls with art by Amy Atha-Nicholls and coding by Rob Grundy, X-Clacks-Overhead allows fans to recognize and celebrate Pratchett's legacy whenever visiting participating websites.
