If you've sat through any of the commercials during this season's Thunder games, you've likely seen the NBA Encouragement commercials. The commercial displays old footage of players when they were in high school or college and then superimposes "visitors from the future" to either comment on or even interact with the past versions of players such as Kevin Durant, Chris Paul, and Stephen Curry.
At the official NBA blog, they have posted some of the raw footage so that you can see the technology in action:

Here is the making of the Nash commercial, which is my favorite in the way that Nash actually looks like he's interacting with the kid.
Below I've included the Kevin Durant clip, along with my other personal favorite, that of Stephen Curry.
