Grafedia , created by John Geraci, is hyperlinked text, written by hand onto physical surfaces and linking to images, video, sound files, etc. It can be written on walls, in the streets, or in postcards, on the body as tattoos, or anywhere you feel like putting it.
Viewers “click” on the grafedia hyperlinks with their phones by sending a message addressed to the word + “@grafedia.net” to get the content behind the link.
You can make street art, or just leave behind simple calling cards for others wherever you go. You can have running dialogues between authors, or create interactive narratives in public spaces. Every surface becomes potentially a web page, and the entire physical world is joined with the Internet.
How to do it? Choose a word. Then, send a media file from your cell phone to that chosen word plus ‘@grafedia.net’, e.g. ‘email@example.com’. Write that word anywhere in the real world in blue with an underline. That word will then be linked to the media file the author sent to grafedia.net, and viewers will be able to retrieve the file. You can also upload media from your computer directly to the grafedia.net server to create grafedia with more precise images.
