First, thanks for sharing this with everyone. It looks great!

I have been able to view your sample and am also working on my own. The good news is that it does convert and I can view it. The bad news is that I do get an error. I have copied the message below. Do you have any suggestions as to how I might fix this?

jupyter-notebook-slides$ jupyter-nbconvert --to slides Testing.ipynb --reveal-prefix=reveal.js --post serve
