From Iron Man to the Candy Bar - via the Lego pit...

San Francisco is currently playing host to Oracle's OpenWorld conference.

The event, which runs until Thursday, is a heady combination of hard technical information and geek playground.

With around 40,000 attendees, OpenWorld takes over a big chunk of the downtown San Francisco and it's hard to escape the Oracle branding, seen here on the Moscone Centre.

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.
