The logo for Bluetooth short-range wireless technology is a bind rune made up of the initials of Harald Bluetooth's name using the runes of the younger futhark: ᚼ (H) (Hagall) and ᛒ (B) (Bjarkan). This tenth-century King of Denmark famously declared on the Jelling Stone that he had united Denmark and Norway and made the Danes Christian.
