Photos: Oracle OpenWorld in pictures

This year one of the star attractions at the show is a set of armoured costumes from the recent Iron Man 2 movie.

Oracle appears in the movie as a sponsor of Tony Stark's Stark Expo exhibition, and Marvel Entertainment also uses Oracle technologies to run its business.

Also on display is a model of the BMW Oracle trimaran which won the America's Cup back in February.

And for database enthusiasts with a sweet tooth, there's a candy bar where they can fill up on sugary treats.

Google sponsored a Lego pit where developers could build their own creations in plastic bricks.

Here someone seems to have built a model of the BMW Oracle trimaran.

Out and about in San Francisco it's hard to escape the Oracle message - whether you're on foot, in a cab...

...or on a bus. Even the homeless of San Francisco have got in on the act, adding references to the event to the signs they hold in a bid to up their donations from passsers-by.
