In 2015, in collaboration with Grumpy Sailor, TEDxSydney and the Sydney Opera House, we developed a teddy bear that could talk. In fact, we developed 40 of them. Not only could they talk, these bears could react to their environment, meaning they could tell different stories depending on where they were within the Opera House. Walking around with a TEDdy X Bear is kind of like having a witty, often cute, occasionally rude, teddy bear companion. We created a series of riddles - Our teddies had lost their owners and we asked users to pick one up, walk around and figure out who the previous owner of the bear was. The teddy bears revealed secrets - and little hints - about their formative years. Guess the owner correctly, and a reward was on offer.
