The Fine Line – Ryan Lochte Swimming. (NYT Video-Supported Storytelling)
I quite like how this approach to storytelling/demonstration has been put together.
Sure, they hijack the scrollwheel, and there isn't a lot of textual content on the page, but it is done very well in my opinion.
I thought it would be appreciated here (I have no connection with NYT or this story)
A++, would scroll again.
