Dancing in circles

A little bird just came in through the windows of my hotel room and tweeted that there must be some kind of birthday to celebrate a bunch of km eastward from were I am today. I told him to go back to Stockholm and bring my salutations to Mr Urbano and warn him that ... I might call! :-)

Only for this happening, today I'm breaking two rules of mine: squareness and monochromatism ... :-)

Two thousands years ago, someone wrote: "Semel in anno licet insanire."
