Hatsune Miku: Project Mirai lets you comment on videos

The Streetpass function is one of the more interesting aspects of the Nintendo 3DS and most games implement it in one way or another. In Hatsune Miku: Project Mirai, you can actually watch videos and write comments to them, which can be shared via Streetpass. These comments will then appear in the video itself. Andriasang also shows some picture from the Augmented Reality features.
