Small-ish animated GIF file (5Mb): View it!
When I was close to the end, with 5 pages left, I did draw a few small test doodles so I'd know how to fit everything I wanted in at the end. Up until that point, I was simply generating pictures "by the seat of my pants" (or pulling them out of my ass, if you want a less complimentary description). No pencil drawings just do it in ink. That's why the car sequence looks so weird and the "trees" the car drives by are equally indecipherable.
I managed to finish it in 2 days. Probably a couple hours total, if that much.
Then it occurred to me that I won't actually have a copy of it once I give it back to my friend. I was mentioning that to another friend, who reminded me that my camera has the capability of taking a series of pictures at a programmable interval. So I put my camera on a tripod, used my 50mm prime lens (75mm effective, gives a little zoom factor which works nicely), set it to take pictures once every 5 seconds (I tried 3 and that was too fast) on a low resolution, JPEG mode, and then had it merrily snap away while I flipped the pages between shots. There were a bunch times I wasn't fast enough, but I just let the camera take another picture. Actually, for the last 2 images, I had to trigger the shutter manually, because the auto-sequence had ended (I had set it to take 81 pictures, so there were a bunch of shots with my hand in it). And of course, things moved a little, so they don't look perfect. But it was close enough. So it roughly took 6 minutes to photograph all the pages in the booklet. Not bad.
Then I tried to put the pictures into photoshop, but 70 jpegs of even a modest size turned out to be a bit too huge. So I cut the resolution down using ImageMagick via the command line (impressive tool), and then tried it again. I used the Photoshop scripting capability to read all the files into a separate layer, and then turned each layer into a separate animation frame. I moved a few images around and deleted all of the shots of my hands, and then set the timing. And then I tried to export it, and Photoshop needed about 10 minutes to think about it before giving its answer ("no"). I managed to save the .psd file, since I had already spent time rearranging things and setting the frame timings. It wasn't easy to do, because Photoshop was in a bit of a mood, but it worked. I shut down, cleared some disk space on my VM, then allowed Photoshop access to my external drive to use as extra scratch space.
Then I cut the resolution down again. Each time, I reduced it to 50% of
what it was. And then I cropped the image to further shrink it. That
is the big image link about, 20M of GIF (which was 25% of a low-resolution,
cropped photo). And then I reduced it again to produce the 5M GIF.
All in all it didn't come out that bad, considering how low tech
