[luv-talk] Desktop Mood?

Yes you read right… Desktop Mood, not mode. I was pondering if anyone has done, or more likely aware of some good research, on how the computer or tablet or phone background can have on a persons mood. The colours, the pattern, or picture, etc. Does having a picture of loved ones^^ make a difference? ^^Can include pets. Does an outdoor scene do it for you? And how close to reality does it have to be? i.e. Do Mountain scenes cut the mustard for you, or does it have to be your local park? Thoughts? Or you could be like me… Boring :)
