Well this subject is what i together with my partner in e-learning crime Ferry van Vliet excel in. Subjects that are basically dull and no fun, and still make something fun of it.
So it is hard to choose from the courses we did. At the moment working on a Warranty Training for Harley Davidson. Also a perfect fit for this contest, especially because i made a great solution for a datagrid in it. Might upload that one another time. For now, here are a few exercises/pages we made for Hometrack Online for Heausa ( http://www.heausa.org )
