Electron 1.0

Electron Microscope shader.
This shader will create an electron microscope look to your objects.
The shader uses incidence to darken areas that face the camera
and lightens the edges.(similar to an electron microscope)

You will have to attach a texture projection to the texture node of
the shader.

One infinate light in your scene will create the hot rimm that most
electron microscope images have.

The 'Rock' texture I have attached for the grainy bump effect is just
an example, you may want to try something better suited to the look
you are after.

The 'change range' node is usefull to set your darkest and lightest shade,
and makes it easy to match CG objects against electron microscope images.
