Where could a locomotive accelerate from a fireplace? A possible answer is – this happens in our mind, consciously and/or subconsciously. That is how we formulate innovations, ideas, thoughts, dreams.

Or, maybe so called ordinary lives as depicted by the familiar room and fireplace are full of magic and mystery, we just need to open our eyes to them.
