I love this.
It's an artwork by Knut Henrik Henriksen on the new bit of the Northern Line at Kings Cross.
Can't see it?
My friend Blech has a better picture.
The thing I like about it is that it's so easily ignorable.
It's the kind of thing you might not see for years and then you'd suddenly discover it. And it would bring a smile to your face. It's so elegant and beautiful and now it has been given, by accident or by choice, a position that makes it a hidden gem. A needle in the haystack of the commute.
