While we’re on the subject of user experience, I happened on this collection of UX design aids that I thought you might find interesting. More than anything else, I like the idea that they remind us of the vast number of potential parts and pieces of a modern website. And even this is just the tip of the iceberg.
I like the idea of the playing card versions each representing a website function that you could lay out on a table and shuffle around when you’re brainstorming the overall design of a new project. Even in the digital age, it sometimes works best to touch and physically organize things.
