Ikea Catalogue
One example of augmented design that I really liked and felt had a good use and not a just pointless edition was the 2013 Ikea Catalog App idea, basically it helped the catalog show different product and ranges that print just couldn't. However, my project is different I am not selling anything and I am holding an event.

Scratch Cards
I found this on pinterest, I don't know whether this would come in useful but I like this scratch card element. It could make the print a lot more augmented/interactive with a scratch card element . I found this link to make your own DIY scratch off card. As my event will be egypt related gold would work really well.

New York Nearest Subway app
When you load the app, holding it flat, all lines of the New York subway are displayed in coloured arrows. By tilting the phone upwards, you will see the nearest stations: what direction they are in relation to your location, how many miles away they are and what lines they are on. If you continue to tilt the phone upwards, you will see stations further away, as stacked icons. Only available to Apple iPhone 3GS users.
