In regards to the "cold fish", well, let's just say that the situation he finds himself in, and that the reader does, is interesting enough to keep the Analog Writer's Group interested and asking for more.
I'm hesitant about posting anything these days as discussions on other forums seem to have come to the opinion that this could amount to being published in some publisher's and editor's eyes.
In regards to "fidgeting", I understand what you mean and I do try to avoid that. Here's a pertinent section from my book where two characters are talking to one another in a lab setting and one is trying to explain something to another (I don't think that small excerpts like this can be, in any stretch, considered "publishing" of a WIP - please pardon me if placing the example here isn't appropriate),

“Well, it’s a tough call. Photosynthesis is a complex process that works in two different ways, called the light and the dark cycles, respectively.”
“It’s been a long time since I took basic biology, and even then I didn’t concentrate on plant physiology,” Jason said. “But I know the basics. It’s the details of this process they proposed that I don’t get. That’s what you’re here for.”
“Right. Okay, let’s work through the process and see where they might have rearranged things some. In the classic example a six-carbon sugar and six oxygen molecules are manufactured by the plant from CO2 and oxygen. Photosynthesis is a two-step process. The first stage is the light-dependent reaction. The second is the light-independent, or dark, reaction and it’s only called that because it does not require light to function.”
“Right, I got that,” Jason said. He felt the flare of anger in his stomach again.
“The light reaction occurs in the grana of a plant cell,” McIntyre said. He took a dry erase pen and stepped over to a whiteboard to begin drawing. “The grana is a stack of thylakoid membranes inside the cell. The thylakoid is the structural unit of photosynthesis. If they did anything to interfere with photosynthesis, it would likely take place there. Think of the grana as a stack of pancakes. Each individual pancake is a thylakoid.”
“Pancakes. That reminds me, I didn’t have breakfast today and I haven’t had lunch either,” Jason said.
“Pay attention,” Randy said. “This is important.” He drew a stack of circles on the board. “The areas between the stacks, the grana, are called the stroma. In the light reaction, light excites electrons in the chlorophyll, raising their energy states. An electron transport cascade then uses the energy from this reaction to synthesize adenotriphosphate, ATP, or nicotinamide adenotriphosphate, or NADP. Water is split in the process.”
“So, there’s our hydrogen, right?”

This scene takes place in Chapter 21 and is about 1/3rd of the way into the book, but is placed here to demonstrate what I mean when I'm trying to have my characters perform some type of action during dialogue (in this case, it's also important to the scene).
BTW, you can call me Greg. The FOTS portion of my nym is short for Fire On The Suns, a space opera wargame played via email which I've been running for about 15 years.
