Basic Hologram - Just a Fresnel (rim) lighting effect, with basic color and texture capabilities.
Scanline Hologram - Apply a scanline texture which multiplies the alpha component of the hologram so that it only appears in lines. Change the speed and thickness of the lines however you want.
Glitch Hologram - Shift individual vertices over time by moving them along their vertex normals for an imprecise look, or offset a rolling window of vertices in the same direction for a brief moment to look like your hologram is experiencing severe display errors.
Grid Hologram - Overlay a grid pattern in world space onto the hologram, with the option to scroll the lines or display them with different per-axis strengths. Also with an option to apply glitch effects.
Dot Matrix Hologram - Convert the hologram shape to a grid of dots aligned in screen-space, with optional glitches.
Gradient Hologram - If a basic color isn’t enough for you, then you can mix between two sets of base color and Fresnel color, blending based on height in object- (model-), world-, or screen-space.
Noise Hologram - Add a layer of Perlin noise onto the hologram surface for a fuzzy, lo-fi look.
Uber Hologram - Combine the features of the Glitch, Scanline, and Noise holograms for an intensely stylized appearance.
