Plenty of selfie action going on at last night's opening ceremony. 

Not your bag? Swipe along, nothing to see here...

Denmark's Caroline Wozniacki's caught up with fellow tennis star Rafael Nadal - who carried the flag for Spain last night. Not sure about the hat personally.

While American swimmer and gold medal hoarder Michael Phelps proved to be a hit with the US women's hockey team.

This is the view of the chosen few last night.

Team GB tennis player Dom Inglot kindly videoed what it is like to stroll in the midst of an Olympic opening ceremony.

A steady trickle of Games Makers and media head towards the Olympic Park this morning as we head into the official first day of action at the 2016 Games here in Rio.

I'm off to the Olympic shooting centre in the Deodoro cluster to the north of the city where Scotland's multiple Commonwealth medallist Jen McIntosh is bidding to become GB's first medal-winner in Brazil.

The women's 10m air rifle gets under way at 12:30 BST.

Fair play to you Lyndsey, this takes Terry's Olympic tribute to a new level (see 08:59)...

You are killing us here Timea.

Swiss tennis player Timea Bacsinszky, who plays doubles with Martina Hingis later today, chose not to attend the opening ceremony last night.

But she did stage her own solitary and silent athlete parade in this crushing video.

To the outside world, Australia's outfits for last night's opening ceremony appeared to be something of a grammar school throwback. 

But inside lay a brilliant tribute...

Have a squint and you can see legendary swimmer Dawn Fraser's name in the list.

Wherever you are in the world, Rio is coming at you from the front pages.

The New York Times - with a front-page format that went out of fashion everywhere else sometime in the 1920s - call then "the gilded games in the gritty city."

L'Equipe promises its French readers "a shower of stars" over the coming three weeks.

While Republicca in Italy talking about the ceremony as "hunting in the early hours". I, or an online translation, think.

Not one match but two. Great Britain's women's rugby sevens team get their Olympic campaign going against Brazil at 16:00 BST, before taking on Japan at 21:00.

Captained by Emily Scarratt, the squad includes six players looking to complete an impressive double, having won the XV-a-side World Cup in 2014 with England.

"Even in a tainted era, the Olympics still matter. No global sporting event brings together so many nations; at few other moments are the eyes of the world focused on such a small segment of the planet's surface.

"Over the next 16 days returning heroes like Usain Bolt, Serena Williams and Michael Phelps will try to hold that gold standard once more. Young pretenders yet unknown will rise to become fresh stars. We will scream and shout and care about sports we ignore across the intervening years."

That's just a taste of Tom's blog from last night's opening ceremony. To read more, head here.

As he closed out his speech last night, Rio 2016 President Carlos Nuzman's subconscious livened up one of the slower sections of the opening ceremony by saying that he "always believed in the sex...success of the Games".

Easily done as BBC man Stephan Shemilt can attest. And he did not have the excuse of speaking in his second language.

One of the hardest things to deal with when the Games start can be the boredom. Sitting around with days to go until your event you end up going to the canteen chatting in your little groups, spotting all the superstars and... eating. There is often the problem that, with three hours to kill, you eat too much to fill the time. Have another muffin. You have to be really disciplined.

Coincidentally, how are your Olympic breakfasts coming along?..

Rio 2016 reportedly spent £3m to produce the opening ceremony - roughly a 10th of what was handed to Danny Boyle for London 2012's effort.

And London 2012 was cheaper than the huge whizz-banging cast-of-thousands production that Beijing throw on in 2008.

I reckon they wrung every last cent of value out of their budget.

Here are the best bits if you didn't manage to stay up.

Plenty of Brits to keep your eyes on in the rowing heats throughout the afternoon - all this gets going from 12:30 BST.

• Men’s single sculls heats: Alan Campbell       
• Men’s pair heats: Stewart Innes, Alan Sinclair
• Men’s double sculls heats: John Collins, Jonathan Walton
• Men’s quadruple sculls heats: Sam Townsend, Peter Lambert, Angus Groom, Jack Beaumont    
• Men’s lightweight four heats: Peter Chambers, Jono Clegg, Mark Aldred, Chris Bartley    
• Women’s double sculls heats: Katherine Grainger, Vicky Thornley

The cameraphones were snapping like an angry Amazonian caiman last night.

Here are selfie select cuts from within Team GB.

Spare a thought for the members of Team GB who were still back in the holding camp in Belo Horizonte.

Scotch pancakes are the Olympic rings. This brilliant arrangement is only let down by a mysterious absence of maple syrup...

All that grease reminds me that we are after your Olympic breakfast this morning.

How are you getting hyped for a three-week sport onslaught?

Are you sporting a 16-foot Carnival feather headdress for the duration? 

Are you maintaining your own Olympic flame in a kitchen-sink full of lighter fluid?

Or at least bunging out some Union Jack bunting?

Tell us - or best of all show us - with a tweet and a pic to #bbcrio2016, external or just a really vivid text description to 81111 from UK phones.

No doubt who the surprise hit of the opening ceremony was though.

Welcome to your 15 minutes of fame Pita Nikolas Taufatofua.

Tonga's flag-bearer carried out his duties topless and with enough baby oil sluiced over his taekwondo torso to risk becoming the first human Olympic torch.

Twitter was a'flutter.

As an athlete you just want to get on with it now. You are going into the Olympic Village where there are so many distractions, so many things that could go wrong - you could wake up with a sore throat for example.

You just have to go in, think you're at 100% and let things happen. And if somebody like Chris Froome can get a British medal on the first day that will really help the whole of the team kick on. We need a good start.
