here why i think this is bogus:

1. twitter is a platform where spontaneous messages, thoughts, findings, fun facts and any type of content can be published, without the overhead of formulating a big chunk of text e.g. a blog. twitter is great to publish tiny little bits of content that are greatly incoherent. people love twitter because others remind them of stuff they did not think of and pull them a little aside from the usual dirt tracks they use in their every day online life. do not post the same stuff over and over again.
2. there are already platforms out there that offer a way to publish content in different ways such as video or photo sites: youtube, flickr, picasa, vimeo, etc. these platforms offer a great variety of services that users can access mostly for free. this includes distributing their content and making it accessible to others via different ways and formats: standard HTML (normal web surfing), RSS and atom feeds and maybe an API. use it!
3. one should not abuse a service for something it’s not! this is definitely the case when you use twitter to divert a RSS feed as i did. let the original service serve its RSS feed. this way people have the choice to follow your contributions on another platform if they wish. post a message on twitter that you offer a RSS feed about a specific topic and people can get it from there.

to sum it up: follow my daily image here if you like. subscribe to my blog via RSS or Atom feed. i even have a youtube feed.

let me know what you think, post in the comments or send a trackback.

if you don’t know what RSS is read on on wikipedia about RSS and Atom feeds.

the camera i used is my canon ixus 750. since the lense on this camera is rather low i had to improve the camera stand. i added some aluminum ducts to make it higher and to make the camera see the street. about 7 centimeters were enough.

since i was not able to get the CHDK timelapse to work i shot video. to generate a timelapse i used ffmpeg to extract images out of the video and to unite them to a timelapse video.
using this tutorial and the man pages i was able to come up with this:

#!/bin/bash
# sample usage: ./timelapsify.sh input.avi output.mp4
mkdir ffmpeg_temp
ffmpeg -i $1 -r 1.4 -f image2 ffmpeg_temp/%05d.png
ffmpeg -i ffmpeg_temp/%05d.png -sameq $2
rm -rf ./ffmpeg_temp

note that it is important for ffmpeg to have the images you use to generate the timelapse video in order and sequenced. if you decide to delete some images you have to rename them and must not leave gaps.
also you may have to vary the rate (i used: 1.4) acording to the speed of your input video and the speed of the output video you want to have.

one step i did between extracting and generating the timelapse was sending it through imagemagick to blend the speedometer. using info from this mailing list:

#!/bin/bash
#usage: pixelate_circle.sh IN.file OUT.file center_x_coord center_y_coord border_x_coord border_y_coord
convert $1 \( -clone 0 -scale 10% -scale 1000% \) \
\( -clone 0 -gamma 0 -fill white \
-draw "circle ${3},${4},${5},${6}"\
\) -composite $2

of course this has to be done for every image

and here is the resulting video:
