The imagery in this story is very vivid, and I can really feel the sense of urgency and excitement that Marvin is experiencing. The way you describe the flicker show is especially well done, and I can almost imagine the images that are flashing on the screen.
I'm also interested in the way you use color in this story. Crimson is a very powerful color, and it's used to great effect here to create a sense of danger and violence. The way you describe the way it "floods" Marvin's thoughts, surroundings, and loins is really effective.
