@clacke Didn't automatically jump out as Swedish, possibly diluted by other places you've lived and if you learned English via someone with a particular accent. Slight hint of German, maybe?
I've watched Mentour pilot before and I'd definitely spot him as Swedish, similar accent as the guy who does the Wintergatan music machine.
agree with @alysonsee - I work in a uni with colleagues from all over the world and the variety of accent is a joyous feature, not a bug.
