Old style LCD displays (clocks and stuff like that) sometimes have layers of polarized plastic sandwiched between the glass lcd display. If you hold the bit's of plastic up to the light and rotate them it go's from transparent to black. You can hook a LCD to an arduino and see it work you can also experiment with polarized plastic. I could be wrong here but isn't the polarization of light a quantum level effect.

No it is classical physics.

Still, different color lights should make different voltages out of a cadmium cell shouldn't they?
No the voltage is a function of the cadmium. With the photo electric effect you need to do it in a vacume tube so you can measure the voltage of the ejected electron.
