In the E-LANE project, we have created a first version of a .LRN tutorial using animations (only spanish version is available). This is at:

Greetings, Pedro
How long did it take to produce them? Which tools did you used?
The animations have been made with Macromedia RoboDemo version 5.0
It took about 100 hours to produce them (including learning how to use Robodemo)
