Curvy Bendy Architecture

Do you know, I've been blogging so long now, I can't remember if I've shown you these pics already, but if so, probably not in this combination.
And they bear looking at again anyway!

A tube tunnel looking like somewhere from inside the Tardis.

And window and roof-y bits from other areas of London.

Walk into the Light! One of the tunnel crossings near Greenwich, I think.

There's always something odd to photograph in London.
