Fifa has announced that the football for the next World Cup, in Brazil in 2014, will be called the "adidas Brazuca".
So this competition is to create the design for the new ball including, if you see fit, a special edition version for the final. It's just-for-fun, the ball won't get made and it's in no way affiliated to Fifa, adidas or the World Cup organisers but it's worth having a go all the same.
For obvious reasons all entries should have adidas as manufacturer but everything else is up to you. White with black or multi-coloured? Gold for the final version? As usual, anything goes, and don't worry about the physics of it - we'll leave adidas to try to get that right this time.
As is standard with DF competitions, selected entries will be featured on the DF facebook page and tweeted and, if there somehow are designs already uploaded to the DF galleries, they are both eligible and welcome so please don't hesitate to include them.
The competition will close at 23:59 on Saturday 22nd September 2012 and the winner(s) - chosen by me - will be announced shortly afterwards.
Update - 23/9/12: This competition is being extended due to the small amount of entries so far. No closing date will be put on the competition until there are sufficient entries to announce a deadline.
Update - 26/12/12: This long-running competition will finally close at 23:59 on Saturday 5th January 2013 and the winner(s) - chosen by me - will be announced shortly afterwards.
Update - 8/1/13: Finally, this competition is closed. I asked for something a little bit different to the other competitions and although there were only a modest number of entries, we saw some great ideas.
As altra says in the description for his impressive effort, he "wanted to try out designing a sphere and it's pretty damn hard!"
So MartinLeRoy deserves extra credit, and the winner's spoils, for firstly coming up with a fantastic design, apparently an evolution from the Jabulani but with unmistakably original and very imaginative features, then a special World Cup Final version, and then the standard version viewable in 3D and rotatable. A worthy winner I'm sure everyone will agree.
