Extracting embedded images from SVG

With Inkscape, one can open and edit PDF files. But when the PDF comes with embedded images, the resulting SVG keeps the images as an embedded base64 encoded data. I wanted to extract those embedded images from the resulting SVG. But I didn't want to use the "export bitmap" option on Inkscape to extract those images, as within this way I wouldn't really know the original resolution besides the fact that Inkscape would re-encode the image data. So I wrote this one line to extract all images from one SVG.

i=1; grep data:image test.svg  | cut -d "," -f 2 | cut -d \" -f 1 |while read line ; do echo $line | base64 --decode >  $i.png ; i=$((i+1)); done 

Now, the kid's time

After my little experiment wit clay stop motion animation (link), I brought the camera home and showed the process to my kids... My older son wanted to give it a try... And here is his first movie.

Clay stop motion

A colleague from just the neighbor lab found an old webcam, which has no support (driver) for his Windows 7... He asked me to try to find a Windows 7 driver or some driver which make the cam work for him... As I use a Linux workstation, I've just plugged the camera into an USB port to see what do I get. The camera worked pretty nicely...So we've launched "Cheese" and grab some pictures of some clay that was laying around... It took less than 5 minutes to make this small animation...
After that, he forgot the windows driver and he lent that camera to me to play with the kids.
