Back in early October me and my mom visited Krogstastenen not too far from where I live. It's a runestone from the 6th century with two one-word Proto-Norse inscriptions on the front and back sides, and on the front there is also a carving of a man holding his arms up. What the word on the front, "ᛗᚹᛊᛇᛖᛁᛃ" ("mwsïeij"), means is unknown, but the word on the back, "ᛊᛇᚨᛁᚾᚨᛉ" ("sïainaz" or "stainaz") probably means stone. The meaning of all of it together is of course not known.
I find it pretty cute. My personal (unqualified) guess is that it has some type of pagan religious meaning but who knows.
