Here's a cut-out from the crash screen:
EDivByZero : Division by zero

The rest's the last frame from the game. I still have it if it's of any use.
Everybody should note there are only about 16 possible colours.
Regarding motion trackers-
I don't think it should double move cost. If it's one like in AVP, it doesn't seem to be hand-held, and attention is given to it for split seconds at a time, based on the audio ping. That said, I think it'd be a good idea to have three modes, on the lines of ignore/off, listen and study - ignore/off means the char isn't paying attention to the tracker, "listen" will pose only a small burden but will only give a very general warning (at most a general direction), and "study", which will only apply to appropriately designed trackers, will allow the char to carefully examine the tracker's output, noticing also vaguer signals. Perception will improve player reaction to the tracker, reducing penalties ("listen" should cost nothing at basic perception or so, IMO). Technical skill can enhance a tracker's capabilities through tinkering (or repair an otherwise useless one), but shouldn't give bonuses to on-the-run use (unless simple hardware malfunctions, like insufficient battery contact, are implemented, which could be nice :) ).
EDIT: as I was writing this, DaEezT's post came in, with a serious balance issue. So, how about this: directions only, using a system like one of the more elaborate ones discussed on the "hearing aid" thread for DoomRL? Signal types are based on size crossed with current speed/action type (workers are supposedly doing something when they're standing around).
And one last thing for the moment - could primary weapons be displayed as a '\' instead of as a '/'? I haven't seen a heavy weapon yet, but assuming they're also a '/', could that be changed, too? Maybe a 'X'?
