Oh, didn't know they were all gone. 

I sat down and wrote a script myself. It's somewhat specific to your Squeak image/projects but I'll cc etoys-dev anyway, maybe it's useful to someone. I used the image and projects from

	http://karma.sugarlabs.org/Squeak.tar.bz2

The attached script needs a bit of hand-holding when running inside Squeak. Or just download the assets I exported:

	http://dev.laptop.org/~bert/OLENepalSqueakAssets.zip

Beware, it's 125 MB of PNGs and WAVs. The sounds have their names preserved, but the images are just enumerated largest-to-smallest. I didn't bother to check for duplicates.
