Kuwaiti game developer Omar Khalil is in the process of building an augmented reality and location-based app called Artopia, which allows users to create and save 3D paintings out in the world. Others can then encounter the paintings, which are timestamped and show the username of the creator. Khalil began working on the project as a computer science student at American University of Kuwait. As Artopia nears completion, Khalil is looking for beta testers. If you’d like to give feedback, you can sign up on Artopia’s website.
