Well, Toy Story is going 3D!
It's been announced (and reported at http://news.bbc.co.uk/1/hi/entertainment/7208861.stm
) that Pixar are going to be re-making Toy Story in full stereoscopic 3D! No idea exactly when it's going to be released- except before Toy Story 3- but it should be sometime in the near future.
If it gets released on DVD (or *cough* legally online) then it could make a pretty impressive way of showing the kids Stereo- I'm pretty sure that Beowulf wouldn't have been entirely suitable for the young ones
Along with Beowulf, U2 in 3D, Journey to the Center of the Earth 3D and a whole host of other flicks coming out in glorious Stereoscope, Stereo video is bound to catch on! Expect Stereo Youtube any time soon!
