This is a wonderful app. I will use it every day!
It also picked up the colors in my aloha shirt perfectly. (Anyone who knows me knows that I am to aloha shirts as Steve Jobs was to black turtlenecks.)
When I want to feel young and go shopping for shirts, now I know what to do!
But it also scores me high for anger and sadness, despite (what I thought to be!) a rather neutral expression. Perhaps it knows more than we think :)
Though I'm guessing it gets a lot more accurate when it can take and average multiple shots.
