This is a contribution to Donald Clark's post; I just am not sure how to upload pictures in a response.

Readers of Simulations and the Future of Learning will recognize this picture, from a now-defunct e-learning company called Pensare. (I think this picture was done in 1998).

I always loved how sweeping and ambitious it was. I would strongly encourage any reader to click on it and really look around. In fact, make a poster of it and hang it on your wall!
