I like this a lot, Conan. You'll have to tell me how you did your CRT shader. :)
I love the server drop mode. :)
So, there's no shader :)
The 'scanlines' are a complex CSS linear gradient pattern, and the bright text with color fringing is an abuse of the CSS text-shadow property.
Ordinarily I would use a GLSL shader - I wrote one based on Timothy Lottes' code a while back - but I wanted to do this entirely in the DOM. So it's all standard HTML elements and CSS.
