I like this image supposedly from a Mercedes Benz advert. I don’t remember the ad, I saw this image first on a HD wallpaper website. It’s a marvellous visual feast of colour exploding on the right hand side and simplicity and control on the left.
It appeals because it is two sides that every one has (obviously) and we should remember that regardless of what anyone else says, we are all humans and by nature complex beings. No one person inhabits or exhibits only one side of their brain, personality, intelligence.
