Description from store
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

- (2025-07-14) Jóhannes Birgir Jensson: Does not read correctly from some websites that do have a X-Clacks-Overhead, which another, now discontinued extension, did display correctly
- (2025-04-08) Wild Calendar: Nice visibility of the icon but the detection of clacks messages only seems to work on most sites with the message.

- (2022-03-02) Michael Campbell: Seems to be working for me. Most sites don't have it but I tested it by going to Discworld Emporium and it lit up as expected. A shame it doesn't light up on this page, but I blame Google, not the developer.

- (2019-05-22) Shonaigh Douglas: 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!

- (2018-12-27) RC: 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
