René Descartes and I

In his ennui he tried to determine the movement of the spider, and in the process made up the two - coordinate system which later on became the founding principle of the Cartesian Plane. I tried to dig this story on the internet but could not find it and today I do not even recollect who told me, perhaps my mathematics teacher?

I look above and there is the bright white false ceiling above me, where there is a play of lights from the (non functional) french windows ... but, no, no spiders here in this room. Why spider, no other insects either, to invigorate my mind with their mysterious movements. Even the play of lights is also dulled by the bright artificial lights inside that forever seem to be switched on having an as yet undetermined deleterious effect on my convoluted circadian rhythm. But I do remember this story clearly about René Descartes and wonder if it was just a figment of my imagination from a muddled up childhood memories?
