I remember using it for a while. Then I found Lejos. I have two NXT bricks, although one of them has a broken screen :(
That looks pretty neat! I might run through the tutorial and start learning it if I can think of some more projects...
Yeah I only have 1 brick (from the NXT 2.0 kit), and a lot of technic pieces from my childhood ranging from motors to pneumatics to RC stuff to gearboxes.
My current one is an all-Lego (Technic/Mindstorms) robot that can solve a 2x2x2 Rubik's Cube. I learned all the algorithms, have a some-what solid idea on how to build it, but writing the code isn't going to be that easy. I won't get too involved mainly because I am not sure how to approach it (programming it) yet, seeing that there aren't any 2x2x2 solvers on Youtube (and this isn't exactly the topic for it). I also really want to stay away from any third-party software to do the solving.
