Really like the idea of this, but I'm not sold on the accuracy. The example pic for 'angry' looks very much like someone pretending to be angry and is actually having a laugh, all you have to do is look at the eyes.

Would be interesting to hear from the developers of this on the extent to which the eyes and eyebrows are used in the analysis.

Noticed the same thing. But if you had to choose between putting that photo in a folder called "angry faces" or "happy faces", what would you choose? Of course, you'd hope the software would really be fine-grained enough to detect fake moods so you don't have to make that semi-arbitrary decision, but since it can't, I'm pretty happy with "angry".
