Prism

I sit, early morning, watching a rainbow move across my desk. Subtle, ethereal, a glimpse of nature in it's purest of forms. The cold light of autumn is being split by some invisible force, some all powerful object. The small spectral slither is like the breath of a fairy; playfully blowing over objects, without disturbing them. The lit shadow is beautiful but so tenuously ephemeral. How long will it last? Will it return? I want to savour this moment for as long as possible. Appreciate it for it's simple glory.
