In the past as a GM, I have used pictures to lend a helping hand to my players' imaginations, and mine as well. For instance, when the team took a trip to a Saeder-Krupp orichalcum mining facility in Antarctica, I showed them this picture of the real-life Amundsen-Scott South Pole Station with the Aurora Australis blazing overhead:

You'd have to ask them if it helped them visualize the setting, but I know it helped me. And not too long ago there was a thread (that I can't find now) of other real-life pictures people have used in campaigns, like those massive sewer tunnels in Tokyo or the AT&T Long Lines Building in New York:

But I'm also talking about pictures we've made or modified, in addition to ones we've found on GIS. I'm curious if anyone has come up with some truly Shadowrun-specific to wow their players, or even as a player to show the rest of the table what you're talking about.
For instance: right now I'm playing an AI character who, in his newly-emergent naivete, is lacking in understanding of social norms and finds that his (I'll use male pronouns for simplicity and clarity, here) personality and sense of aesthetics often clashes with and disturbs the metahumans around him. As he comes to realize that people are weirded out by him, he is beginning to delight in being intentionally creepy, even making a hobby of it. He refers to metahumans as "meats" or "meat-organisms" and often makes vague, megalomaniacal statements that might evoke worrying correlations with Deus and the Renraku Arcology. But the entire point of this is the images I use to visually describe his personal sculpting of his home node and his programs, that of abyssal deep sea creatures, typically microscopic ones greatly enlarged: copepods, ostrocods, hexactinellid sponges, and the frightening phronima. I'm not sure if the disturbing similarity to insect spirits is lost on him, or if he did it on purpose. In any case I feel these images accurately and sufficiently convey the very alien mode thinking even metasapient AIs have.
Here are a few images I've made, if other people want to use them in their games. They've been resized and tinted a nice matrix-green hue, but I've got full-size full-color versions if you'd like them. I'll put up some more later if people like these.

Edit: Huh, I guess the forums don't like images? I'll just link them all.
