Feels great to my eyes. The non-blurred square looks far choppier and eye-straining by comparison. Would love to be able to easily add this effect to CSS3 animations since it'll probably be awhile (3-ish years?) before WebGL is more commonplace.

I thought so too, so I wanted to experiment with applying the same type of (physically-accurate) motion blur to scrolling text.

I've realized the effect in motion looks quite nice, but it HAS to run at full 60 FPS at all times. If there are dips in the framerate, the effect is horrible (partly because the 16.66 ms number is hardcoded rather than calculated). My implementation is very naive and not optimized, but it funs well with a dedicated card. Not so much with Intel 3000. It was just a mockup so I didn't develop it further for now.
