YouTube annotations make for a choose your own adventure

Via AdverBlog:

Samsung just launched an online campaign to promote the supposed iPhone killer, the Samsung Instinct. First there is a campaign website including a fun product placement programm. But more innovative is the interactive short movie ‘Follow Your INSTINCT’, which can be watched on YouTube only. The movies are connected through YouTube annotations, which makes it the first commercial use of annotations I’ve seen so far. Pretty cool, simpel(sic) and interactive.

Take a look at http://www.youtube.com/watch?v=HoOCiaxIZF4 .

It’s almost like choose your own adventure, and makes me ponder how we might do something like this for a library video tour. Thoughts??
