Don’t leave home without it.

It is amazing how many retinal shape changes must be happening with the cyclical repeating process of trans going back to cis. I notice from your wiki link that photoreceptor cells are shaped as rods and cones, bringing us geometrically back to pi

I am glad you like the picture. It was created by Design Fusion

One of my favourite pi-systems is retinal, a form of vitamin A (http://en.wikipedia.org/wiki/Retinal). It’s the light-absorbing pigment of rhodopsin in our eyes. It starts off bent (cis) but when it absorbs light, it straightens out (trans) causing a signal to pass down the optic nerve to the brain.

Love the picture by the way. Cocktails chez Amethyst must be a blast…
