Take part in an augmented reality drawing workshop and create 3D digital art that you can only see with your phone.

Join a group workshop (running regularly throughout the day) to get the hang of the app; then make invisible drawings with your phone that take up real space. Scribble safely on artworks, draw with a friend or just doodle around the building; it’s all about time, space and waving your arms around. Finally capture your creation on a ten-second video to share with the world.

Our assistants will be there to help you tell the story behind your drawing - and they'll have some fun single sentence drawing challenges to take if you want some inspiration.

We'd love you to share your creations with us, so we can make a gallery of all the amazing things that appear in the magic digital space - and share them on social media to show the world.

You'll need to bring a compatible phone or tablet (iPhone 6s / iPad 5th Generation or later, with iOS 11.3 or later; Android device running v7 Nougat or later) and download 'Just A Line' before the event from https://justaline.withgoogle.com
