I love this so much! This is such a cool hack, just for the sake of it. Amazing hacking and amazing art! In the preso, she has said the full size output is on the website- can anyone see what that link is? I didn't find it on the video page, but I might've just missed it.

#13Basically the inverse of https://daniel.lawrence.lu/photos/ or https://trains.jo-m.ch/ ;)
...and both got the same weird artifacts, as it piled "similar" slices together then jumbled up "complex" slices.
Too bad they can't have a toggle for time-slice based panorama vs scene-based panorama. or maybe turn on accelerometer optimizations or not.

#14Put down two model railroad straightaways next to each other, with two locomotives, use them as a base to attach a 3d-printer arm across and "print" a model railroad diorama, incrementally moving the locomotives to print each slice.
In other words, a flatbed 3d printer where one axis is the locomotives moving across your railroad layout. I think it could rejuvenate model railroads if you could print mountains, towns, streambeds, roads, etc...

#15Well, on a straight section anyway, if you turn, the inner/outer edges will appear differently-spaced...
Wouldn't do anything positive in terms of suspicious staff though. They might think it's like some kind of heist-movie that will involve a specialized glass cutter making a circle on the window.

#16It would have been pretty easy to use a horizontal line scanner to get image speed. In any case, it seems that using a full frame video would be much easier to post process since frame to frame correlation tells you everything you need to know about motion.

#18When I read the title I thought of another IDEA that I've had bumping around in my head that would be pretty cool. Put down two model railroad straightaways next to each other, with two locomotives, use them as a base to attach a 3d-printer arm across and "print" a model railroad diorama, incrementally moving the locomotives to print each slice.

#19they need to connect with the skunkworks team, they solved this problem on sr 71 long time back !
this is easy with a roll of film and a slit for an exposure window. you have the lens and the aperture and focus and all of that, but instead of a full frame, you mask it down to a small slit. slowly pull the film across the slit when it's time to capture your target. captures are limited only by how much film you can fit on a reel and feed through the camera during flight. I would expect that miles of film could be carried on the SR-71 without problems. You'd need (I assume) some custom machines to develop that film properly and to produce prints, but that's not a challenge for an entity that can design and build an SR-71.

#20Random thought: If you stick a very small adhesive mirror to the outside window before boarding, then footage "looking down" at the regularly-spaced railroad ties could contribute to information about the current speed and acceleration. Well, on a straight section anyway, if you turn, the inner/outer edges will appear differently-spaced... Wouldn't do anything positive in terms of suspicious staff though. They might…
