Every year, comic book lovers and sci-fi fans and a smattering of entrepreneurs gather in San Diego to geek out at Comic-Con. With this comes a plethora of crazy social media postings, which we've assiduously included below. From the odd to the really odd and even a celeb sighting or two, here's a look at this year's Comic-Con in photo tweets:

Fans can find real life versions of their favorite video game, comic or show.

Assassin's Creed allows fans to participate in a life-sized version of the game, and leap off a tower into an airbag at the Ubisoft installation.

Batman fans rejoice: Thanks to Fox, you can zip line through a mini Gotham City.

Hunger Games fans can have a real-life encounter with the Peace Keepers.

A headless horseman awaits guests (some less than impressed) outside of a mock Sleepy Hollow.

Fans can get a glimpse of their favorite movie sets in real life, including this space pod designed for Marvel's Guardians of the Galaxy.

Even Lego contributed to the event with this statue of Marvel Comic's superheros Rocket and Groot.

Whole families are joining in on the fun.

Dedicated attendees sleep outside with high hopes for accessing the next day's events.

Of course, who wouldn't want to dress up like characters from the Blockbuster franchise, the Hunger Games. Here is Effie Trinket from the movies.

And let's not forget female superheroes...

There was a geek chic fashion show.

More superheros! 

Not everyone is on board with dressing up like superheros, however... There were protestors too.

Plenty of celebs were in tow, too. Jack Black (below) is playing R.L. Stine in the upcoming Goosebumps movie, set to release next year.

Matthew McConaughey even made an appearance.

No word on a proposal yet, but we're hopeful!
