The document proposes three ideas for a mobile app about Aubrey Beardsley and design history: 1) A platform game where the player controls Beardsley collecting artwork to learn about his life and influence on society. 2) A game allowing players to choose different designers like Beardsley to collect art and educate about London design history. 3) An informative app using Beardsley's animated artwork to virtually tour a gallery, providing biographical information and artwork details to support viewers.
