Wow – what an awesome set of concepts! Thanks to everyone for taking part by uploading their ideas and building on others. We've had such a tremendous response that we're extending the timeline of the challenge and have put in some extra phases to help strengthen concepts even further.
Thanks for all your applause – this phase has now closed. Please head to the Evaluation Phase where we'd like you to answer some questions to assess the top 20 concepts for their awesomeness.
