A Geiger counter for Google emitting a sound for each request that goes to Google.
OTHER License
This is a (Firefox) add-on (WebExtension) that emits a sound every time you connect to a service hosted by Google.
It is inspired by @berthubert's googerteller that you can use outside of your browser to do the same.
This is a fun project, don't take it too seriously!
Note: Find it ironic or not, but to query the list of all Google IPs/subnets, this needs to contact one Google domain, actually. (That request does not emit a sound, though.)
