This in combination with the software (Microsoft was it?) that composites photos of people eliminating ones where people aren't smiling or are blinking would be epic.
Kinda seems like how humans perceive scenes - our brains somehow block out wire meshes, or raindrops if we are looking through them.
I believe it was the Photos app in the Windows Live pack that you're thinking of. Haven't used it in ages but it was a pretty streamlined way for non-experts to quickly edit snapshots like that without having to do more complicated stuff in Photoshop.
Not sure if the current photo app does anything similar (or even if Adobe added something like that to PS/LR) but definitely effective if the source images were all similar (as in burst photography).
