The three topics that I revealed from the mysterious blue box were:
Character - Inventor
Environment - Desert Island
Prop - Skipping Rope
My first ideas are still pretty generic such as the Inventor is involved in a plane crash, ends up on a desert island, has to invent a means of transport to escape, finds skipping rope in washed up luggage, crucial prop to make the transportation function. I'm hoping that more 'outside the box' ideas will spring to mind very soon.
