Colourful tags on the railway arches

Colourful tags on the railway arches

Deams in action

Bits of Liverpool Street station behind railings

Lord Nomad and more Deams graffiti

A Devil Dog and other graffiti

A big silver tag saying Bribe

Sometimes the simplest tags are the best: arse

The criss-crossing tracks into Liverpool Street

SwiftKey's 100 million cake

There's cake and a load of Pret sandwiches

SwiftKeyers mill around the meeting room

Alex Kipman, head of AI, cuts the cake

The other Alex looks over with a hairy eyeball

SwiftKey's cake has been chopped up

A horse and cart waits at the lights by Hyde Park

Henry & James estate agents - very fancy

Garden party guests head to Buckingham Palace
