2D barcodes in mobile interaction

you can use 2D barcodes like QR codes as trigger points for mobile guides and games. the app you make doesn’t really care what is stored in each barcode, just that they are all unique. so my suggestion is to make the barcodes all point to a description and download page for your app, so if someone scans it with their phone, they are prompted to download the app and join in the fun.

to make your 2D barcodes unique while all pointing to the same web page, you can use anchor links e.g. #anchor at the end of most urls. as long as these anchors don’t exist on the page, the link will work, but won’t vary.

the example barcodes here is taken from the qr code scanner in the app furnace online editor.

Oatmeal Monday

Cooked porridge in homage to Meal Monday (traditionally the second Monday in February):

During the 17th century, Scottish university students lived in very basic accommodation and were required to bring their own fuel, faggots or peat, to maintain a fire. Their diet was meagre too, largely consisting of oatmeal, which they would make into porridge. … As the students’ country homes or farms were some distance from the city Universities, an occasional long weekend was scheduled to permit them to replenish their supplies.
