Expert and non-expert perspectives

Tom Stafford at Mind Hacks has posted a neat demonstration of how learning affects perception.

This sort of demo is useful in explaining to designers why interfaces that are perfectly logical to them (with their expert knowledge) can sometimes be difficult for new users to understand.
