I played around with a couple of the apps, Snapchat – which I already have used, which my friends use alot to microblog about their day with images and video – they love a filter.
I also took a look at Just a line, which I hadn’t used before and this was interesting by drawing onto the physical world using augmented reality. I can actually see this being useful in a more professional environment (even though its nor necessarily designed for that). For example, on building sites pointing out faults for QA purposes, or proposed changes within offices or at events of where things should be setup or changed, etc.
Even within my work, where I want to highlight or mark ICT equipment within a Comms Cabinet or Server Room.
