A quick try using my six-year-old daughter in her Mulan facepaint. Nikon D3 on continuous low shooting mode, walked round the front of her in a two-three second burst.
Not exactly the "Matrix" effect I might have half expected. More bafflingly though, despite being taken in a pure sequence, when I press the "play" button it doesn't play the pictrures in sequence, which massively spoils the effect.
Using "." will show you the images in the sequence I took them and is more like the effect I had in mind.
Overall verdict: I'm sure it's really clever, but, er, what's it for?
