Imagine trying to explain to a kid that this one computer is actually a bunch of computers and why that is cool vs. having a bunch of flashing lights visually showing the work being done in a way that they have never experienced before. Which do you think would be more engaging?

> Other than that they can't run this at home because of the cost?

Do you really think that, as an example, a middle school student is going to be able to go home and install virtual box on their home computer? If they even have one?
