Send a wish in a paper boat...
Create your own wishboat by entering your wish, then find your boat in the augmented reality viewer and launch with a tap.
Your wishboat will circle and then make its way to Queen Street in the centre of Cardiff, where the old Glamorganshire canal lies buried below the streets.
Here your wishes and dreams will be released to form part of a bigger wishboat which you can visit in person or see at wishboatapp.com
The wishboat app is part of a project by Sean Vicary and Steve Knight for Arcadecardiff and the 2014 Cardiff Contemporary Festival.
