How about the creepy dude spying on Naomi and Holden in the bar on Tycho? He inspires yet another reference to Canadian power trio Rush on the show: "The Camera Eye" (the fifth track on what's arguably their most popular album, Moving Pictures).

Just last Summer, Surgeons in Manchester performed the first bionic eye implant in a patient with age-related macular degeneration, the most common cause of sight loss in the developed world. The retinal implant converts video images from a miniature video camera worn on his glasses. Now he can make out the direction of white lines on a computer screen using the retinal implant. Fast forward this tech 300 years. I think we're good here. What's interesting is that is shows that he is live-transmitting the footage, which means that his body is basically acting like one big cellular transmitter. Scary stuff.
