in fact, razor 1911 is still releasing both demos and warez. I don't know that they have any in the running for the scene awards, but they are getting ranked.
having a low level understanding of program flow can help in many situations. If you are an extremely lucky programmer, you might be able to live your life only in high level languages, but most that I have met had to get down in the plumbing eventually. Understanding asm will help with that.
You may want to dig through the pixeljoint and way of the pixel if you want that particular style. If you are looking for artists more generally, the tigsource forums have both places for posting portfolios and job offers. I think that polycount forums may have places as well, but I am not as familiar with that one.
The point is that a ton of game artists hang out online, and you can get to them through there. I am pretty sure that some of the superstars do contract work as well. Paul veer did super crate box's animation, and as of 6 months ago was taking on freelance.
However, the artist we hired was an ex-coworker of a friend of a guy that we met at a hack day, so just getting out there and meeting other game developers can help as well.
Regarding costs, it is generally cheaper to hire an artist than a programmer, but not by much. Maybe 2/3 - 3/4 of the cost of a good programmer. You certainly are not going to get solid work for free.
I don't know about books, but there are some similar single chip computers out there. You may want to take a look at the beagleboard and the beaglebone. I think the difference in both of those is a slightly higher cost, and slightly less good gpu (if they have a gpu at all, I am not sure).
I would just get an arduino and start messing around. While electricity is black magic to me, the programming end of microcontrollers is pretty easy to understand.
Rather than the beagleboard and other related systems, I'm now recommending the Trimslice (http://trimslice.com/web/) heavily. Picked one up a couple months ago and I absolutely love it. It's become my go-to ARM dev box.
If you're a complete noob like me and still have difficulty reading electronics diagram, or sketchy on how transistors work, then get a cheap hackable arduino until you're ready for the more adventurous stuff.
HD video might be out of reach, but you can output to TV (see gameduino). Processing is limited, but you can ship processing to a server via ethernet (see nanode). Storage is limited, but you can have SD card shields (or use a remote server). Or how about radio control (see nanode RF http://http://nanode.eu/)?
Plus an arduino might be a nice companion with a Pi/Beaglebord/Trimslice for remote sensors or remote control. or maybe Lilipad arduino for wearable computing apps.
Very slick indeed! Do you know anything like this but more "customizable" (e.g. build to order)? Essentially I want something like Pi but with more RAM and HDD.
As far as I know, those "edge of space" low cost weather balloon experiments are a long way from putting something in orbit. The cost to put something in orbit is in the 1000s per pound range right (http://www.spaceref.com/news/viewnews.html?id=301)? I remember hearing something about ranchers putting up satellites in the early naughts, but I don't know how feasible that is.
Seems like a better solution would be strengthening the protocols, figuring out mesh networking solutions, rather that chucking cisco routers into space.
