What numbers did you base yourself on for the Toy Story claim? I'm curious.
[Update: If it helps rescue me, I found a page about the difference between rendering TS1 and TS3 in their respective times:

It turns out the original Toy Story took an hour per frame to render, whereas Toy Story 3 can render in real-time (or 24fps, at least.) Given that's probably on a server farm, my claim is still hyperbole, unless you expect cloud processing to be mainstream on all devices by then ;-)]
Assuming a single machine (which is obviously not true, but I can't find any details about the size of the render farm), that'd mean the entire film would take something like two hundred and thirty seven years to render.
Also, note that the WSJ article you linked to is talking about Toy Story 3D which is a re-rendering of the original film in stereoscopic 3D.
However, it was all worth it for your great citation. Thanks!
