Although it sounds like it ‘Greeking’ is not some weird sexual practice practised by the ancients. ‘Greeking’ is a technique that originated in advertising where the potential ad copy or text for a new ad being developed is represented by non-words so that the viewer can focus on the overall design rather than getting caught up in the actual details of the text.
I maintain a digital visual diary in which most days I try to spend some time looking a visual design technique used in all types of medium. I have a subscription to Press Reader which allows me to access hundreds of magazines from around the world. Any design elements that I like I take screenshots and snippets from magazines or websites that I visit.
