Eagle-eyed shoppers can spot a hidden message in anything, even everyday items like razors, or shop signs, and now tech-savvy sleuths have found a new one.
They uncovered a secret message in the Bluetooth logo, and even though the technology has been around for 28 years people are only just realising.
It's named after King Harald "Bluetooth" Gormsson, who brought Denmark and Norway together in the 10th century and is believed to have been nicknamed after his dead tooth, as the Daily Star reports.
And the logo for Bluetooth is a combination of King Harald's initials in "rune", with ᚼ for Hagall and ᛒ for Bjarkan, combined to make the logo we all know today.
What do you think about the Bluetooth logo? Let us know in the comments...
Bluetooth was designed to allow data to be passed from one device to another at a short-range without a physical connection, and the name was inspired by King Harald's ability to unify two nations.
At first, Bluetooth wasn't meant to mean anything more than a title for an internal code while the technology was being developed.
But due to the other options failing to be unique enough or being unable to be patented in time for the release, the engineers decided to settle with the code name.
The king is best known for introducing Christianity to Scandinavia and at one point he ruled over what is now southern Sweden, northern Germany, Denmark and parts of Norway.
Some accounts imply that his oddly coloured tooth earned him his alternative moniker but others arent so sure.
