It's a design magazine, although compared to Printed Pages it's such a different beast that it seems strange to put them in the same category. IdN is a blur of product design, street art, graphic design, and installations; images fill the pages, swamping the tiny paragraphs of tiny text. As a reading experience it's pretty terrible, but as a design showcase it's great.
My favourite part of IdN is that it also showcases animation. Apparently it used to come with a DVD, but this material has now moved online and is accessed with a password provided by the magazine. This issue's theme is Geometry in Motion Graphics Design and there's a lot of fantastic videos to watch, although my favourite is a music video that can also be seen here.
Would I buy it again? No. But I recommend it as a source of inspiration to designers and animators everywhere.
