NXT w/ LabView

So I got a NXT kit from a colleague at work, and I'd like to start developing some functionality for it. My ideas so far:

• Develop a ultrasonic mapping tool that works on a guided stationary turret (1 DOF now, possibly 2 later) that displays a graph of how far away objects are.
• Develop some control algorithms (including some limited PID controls) for motor positioning. this would be applicable for the classical inverted pendulum problem.
• Maybe some fairly complex line following, I've never been a huge fan of this kind of application just because its not a very realistic real-world solution (and it makes it worse when people think that it is) but it is interesting nonetheless.

This is of course in concurrence with all the other work I'm involved with as well, so it might be awhile before I am able to post any documents. But I'll try to knock this out and see what the NXT can really do.
