Flutterby™! : Perceptual spaces

Had an interesting moment last night, I was helping someone who has done a lot of 2d collage "get" some aspects of video editing. We were talking about video-safe areas and cropping image. Something she said, and then immediately corrected herself on, showed me that she was thinking of video in terms of a progression in 2d space of 2d images, because her quickly withdrawn question was asking about how the edge cropping affected the visibility of subsequent and previous images. Very cool to see that glimpse into someone else's visualization, especially since I've been trying to do some higher dimensional algebra recently and think I'm starting to get past the "visualize lots of separate boxes in 3 space linked by time" issue, but...
