Description

This extension is a tribute to the late Terry Pratchett (https://en.wikipedia.org/wiki/Terry_Pratchett). It displays an icon when the user visits a website sending a "Clacks Overhead" message. If the user clicks on the icon, it will display the message and animated clacks semaphore code. More information can be found here: http://www.gnuterrypratchett.com/ Notes: 1. This extension does not collect any data or send any information anywhere. 2. All code is open source on Github: https://github.com/newfolder0/chrome-clacks Contributors: - Peter Bell (original author) - Charlie Wheeler-Robinson (bug hunting, refactoring, improving in early versions) - Jimmy Nyström (code) - Melanie Wilberforce (icons) - Rob Grundy (who made the Firefox extension) for sending me the clacks icons used in the animation - Backspindle Games for producing the clacks icons in the animation - Sap1ens, jwakely, and Amy Atha-Nicholls (generously offering new icons) - yousuf811 on Github (squashing bugs) - Jarek Glowacki for some CSS help - Jake Heimark (hmk on GitHub) for fixing the manifest and keeping this extension alive in 2024 -See GitHub issues and pull requests for others

Does not read correctly from some websites that do have a X-Clacks-Overhead, which another, now discontinued extension, did display correctly

Nice visibility of the icon but the detection of clacks messages only seems to work on most sites with the message.

It used to be cool, seeing the little icon light up on some websites. Sadly, it no longer seems to work - it doesn't appear in the address bar anymore and the control icon is always lit up. I know there are a lot of Discworld fans, but not that many!

It broke down a while ago and no longer works. Maybe an update is needed?

In the most current version of Chrome ever site, except (humorously) the chrome web store, shows as sending the clacks header. This appears to be broken in Chrome 71. <3
