I Need A New Mood Ring

The mood rings I've seen only tell me what my mood is. This is boring. I know what my mood is. I need a mood ring which produces more information, such as a pie chart which says:

Your mood is

33% hormones. Wait it out.
27% fatigue. Take a nap.
30% annoying people. Get away from them.
10% lack of chocolate. Have an M and M.

There may be additional core categories of mood drivers. I haven't thought of them all. But while I'm sure there is a huge market for this idea, I'm giving it away here on the internet. Please, someone, come up with this ring.
