Great demo!

This is probably obvious, but for the first time it occurs to me that motion blur is essentially the same as anti-aliasing. They are eye-tricking hacks to work around a lack of resolution in the medium -- screen resolution, in the case of pixel anti-aliasing, or "time" (framerate) resolution in the case of motion blur.

Recently I've been wondering if as very high-resolution displays become commonplace, anti-aliasing will become obsolete. If I could play an FPS video game on a 500dps monitor, would anti-aliasing make any perceptible difference? At some pixel pitch, even text anti-aliasing won't matter.

The same thing seems to apply here. If we had 5000Hz screens (and could run our animations quickly enough to keep up), would applying artificial motion blur buy you anything?

Those are some extremely insightful and promising thoughts that deserve more research. If you venture more in those explorations, I'd love to read thoughts you have :)

Disabling anti-aliasing is already recommended as a method to increase FPS on the Retina MacBook Pro for precisely that reason... unfortunately, the details still look ugly if you do that. Non-antialiased text also looks quite decent and is nice and sharp.
