Stress O-Meter Ring
Imagine a ring that could [u]extremely[/u] accurately measure a persons stress, and display it by changing colors (Black= super stressed, green= moderately stressed, blue= no stress). Now, when a friend is stressed out, you know to tread carefully before they blow up and when your friend has no stress you can smack some jokes around. Now wouldn't that be something!
Reward: A couple of these.
