This reminds me of something I saw a while back (it might have been on Boing Boing or something, and I'm sure it made its way across the web) of a guy who had a camera he'd made out of an old scanner. Basically, the scanner would move across the surface very slowly so it captured a slice of time. I wonder if that sort of technique is being used here.

Yeah, that was fun: #starting at 467s and outputting the images of the next 3 seconds ffmpeg -ss 467 -t 3 -i video.mkv output.%04d.png # crop image to 1px slices 280 pixels from the left. gm mogrify -crop 1x+280+0 *.png # stitch them gm montage -border 0 -geometry +0+0 -tile x1 *.png image.jpg Perfect example how easy and straightforward it is to use command line utilities. Now someone just has to find movies with st…
Corollory : One could produce a whole range of image0%d.png from vertical slices through the video, and stitch them together into a movie. Essentially rotating the movie abouts its y axis (in the x-t plane). If we assume 50fps, then every 1000px wide video would become a 3-4 minute short. But movies would require a very wide screen...
I tried that with a Super Metroid run (hoping that the results would be easier to see with a video game):

#33Does this remind anyone else of the Tralfamadorians analogy from Kurt Vonnegut's Slaughterhouse-Five? I can't find the relevant quote...
Yes. It's probably been 15 years since I read the book but that was still my first thought as soon as I read the headline.

#34This is how finish line cameras at races normally work. At least many of the bike races I've been in.
Horse as well. Throw in a well positioned tall but narrow mirror on the opposite side of the track, and you get a full view of how the race finished in a single photograph.

#35Daniel Crooks is an Australian artist who does similar work, but with video as well as still images.

Some of his work is projected onto huge displays which is am amazing immersive experience!

#36A similar volumetric slitscanning technique can be done using XBOX Kinect using 3D data points, here is a video result from an experimenter:
"...this technique uses spatial + temporal data stored in a 4D Space-Time Continuum, and 3 dimensional temporal gradients (i.e. not just slitscanning on the depth/rgb images, but surface-scanning on the animated 3D point cloud)."

#37Hacked up a quick JavaScript implementation of this for anyone to play with: http://jsfiddle.net/soulwire/xKCt4/embedded/result/
It uses Web RTC so you'll need a capable browser (such as Chrome) and will have to allow webcam access when prompted!

#38This is the kind of photo they use for getting a "photo-finish" shot - they have the vertical spacial dimension, and time running sideways.
I have a similar idea for one of the representations of where I'll be speaking:

#39Ward Cunningham and I built something similar with an old Mac mini and an external firewire iSight camera when we both worked at AboutUs a few years back. We pointed it at the train tracks behind the office and got some cool images of trains as they passed by. I don't think we saved any of the images, though -- it was just a quick after-hour hack project.
On a related note, the new Panorama function in iOS 6 seems to turn the iPhone's camera into a slit scanner using the phone's accelerometer for the rotation rate to stitch together a pretty good panorama on the fly.

#40I built a camera like that out of wood a couple years ago. It uses gears on the inside to pull a regular roll of film through and expose it through a narrow vertical slit as you rotate the whole camera on its center axis. It's sort of a broad-stroke photo. http://nnife.com/d/?dimension=33 Here are a few shots that turned out decently: http://nnife.com/p/?dimension=20 These are just film scans. You can by the light ba…
Oh man, those "few shots" are beautiful. Do you have them in a higher resolution?
