HBO is challenging you to create a short text ad (just a 25 character title and a 100 character body, so all in all less characters than your standard tweet) - it would presumably go in a newspaper's classified section - that promotes Ray's "tool" in a clever and non-illegal sounding fashion.
No image creation necessary - you're only allowed to select one of their pre-selected images.
HBO will feature the best ads on Facebook where a winner will be voted on.
