Sorry I cant help myself here thats such a cool pic, its one big metaphor for the traders mind.

The boy and girl standing in that nice green pasture are representative of our manicured and cultured selves which we display to the world. In this instance, all the carefully crafted sophistication is standing aside completely powerless, watching as the clown asserts his dominance over a picturesque scene soon to become a wreck of epic proportions.

Interestingly he is also flipping the bird whilst looking down (hugely dominant) at the genteel and polite looking figures which suggests that he can take control whenever it pleases him.

The train has a malevolent look on his face and appears to be looking straight at the dog (which represents joyful carefree spirit ) with the intent of running it over. The dog could also represent the futility of the contemporary mindfulness techniques that everyone finds so fashionable. He is about to get squashed no matter how much he yaps and tail wags.

Its all so symbolic of our minds. Things can get out of hand pretty quickly and when momentum starts building there ain't much anyone can do about it. Maybe just let the train crash and then go clean up when the clown has gone home

LOL @Grantx, if I ever get over to the UK you'll have to let me in on some of that shit you're smoking
