Yay! Back in the time I gave a seminar presentation on the LineDrive stuff. Pretty good combination of usability (show the user what he/she actually wants to know) and algorithmic stuff (automatic layout)...

More to the point, I always get lost with my own hand-drawn maps (when I'm too lazy to print one) and finally got better at finding places when I got myself a smartphone with GPS and OpenStreetMaps display.
