Unfortunately, I can't read this as the site is utterly and completely broken on my iPhone. I'm usually able to ignore rendering issues but this really takes the cake.
I'm sorry. The presentation was built with Scott Chacon's showoff library (https://github.com/schacon/showoff), which I assumed would handle cross browser issues well. I don't have an iPhone or a Mac, so I couldn't test it there.
It's also broken on my MacBook running Chrome. I can only see the first/title page.
Use the cursor keys (right is forward and left is back) to browse through the slides and I had to go into fullscreen mode to see the comments at the bottom of the page.
A very bad UI. I shouldn't have to guess how to go to the next slide.
Didn't work in chrome, was banging head against wall for almost 15 minutes.
