It was a nice afternoon today, don't you think? The sun warming me through the glass walls of the tram-stop shelter, keepin me from the slight chill winter breeze as I waited for the 109 heading down Vic Parade for a friend's birthday lunch at Quan 88. It'd probably would've been quicker to walk but hey, I couldn't be fucked and besides it was a nice day afterall.

I glanced down at my hand, noticing that some of the light that took all of eight minutes from the sun to reach me had refracted through the glass into a beam of its composite colours. Light itself has properties of both particle and wave, if I remember year nine science class correctly, although I still don't understand it. Humans can only perceive a small fraction of light, somewhere between 380 nm to 740 nm (nanometres) of electromagnetic frequency, which includes not only these reds, oranges, yellows, greens, blues and violets that I can see before me but infrared, ultra violet and goddamn fucking x-rays and gamma rays. I looked this shit up. Thing is, the colours are only an illusion. These cells in my retina like, called cone cells are sensitive to particular wavelengths of this electomagnetic spectrum and in consultation with my brain (no doubt with the assistance of millions of years of jury-rigging) choose to see 'em that way, in technicolour that is. Still, as I rotated my hand, palm up and around through the light I could feel the colour wash over my skin. Strange.

When light passes through something with a different density it refracts, from the air and through the glass, it changes speed. If it passes through, say a glass tram-stop shelter wall, wave forms with different frequencies can separate, refracting in different directions and thus through the funny little cone cells in my eye I see a rainbow.
