5th December 1512
A time-traveller from the 21st century has visited to tell me of the marvels of the age you live in. I am so excited to know that my ideas about flying machines really do work and are used by quite ordinary people. He also told me about the Olympic Games in London and described to me the engineering you did to make a cauldron for the Olympic Flame. Indeed, he carried a little device full of moving pictures which showed me what you had made. I just wanted to let you know how much I admired it. It is a thing both beautiful and functional. You don't need any advice from me but I'm an old man of sixty now and have learned a thing or two about inventions so I'm going to give you some - Always finish what you start. I didn't always do that and I regret it now. Good luck!
