Realism in UI Design
I'm no designer (though I have put together a handful of icons in my day), but the part about too much realism in an icon seems fairly obvious. Are overly-realistic icons actually a problem? If so, a few real-world examples might have been more useful than the fully rendered house icon, which seems far-fetched.Also, I don't really agree with the comment that the icon shouldn't include any details other than the bare minimum needed to convey function. Things like shading/shadows can give icons a more polished look. For example, I wonder if the author would argue that the red/yellow/green indicators in his home button example shouldn't have shading or specular highlights because that's just adding unnecessary detail.
