Photoshop Tennis!
 

Figured we'd go for something fairly open and easy to begin with, just to see if people will actually take part...If so, then we'll move onto more complex things perhaps, like a theme for the round (i.e. headswapping, things that shouldn't be there, etc)

Edit: Bugger it, we'll go with a theme for the first one. Theme is:

UFOs
(not as in, aliens, as in, things you wouldn't expect to see flying over a city)
(...which could totally include UFOs :D)

World Tour



Bid Edit: This is fantastic
