Since the camstudio blog wont let me post anything, without demanding me to be a registered user, and I could not find any email of the project leader(s)/developer(s) Im gonna say through here:
I (re)created a very simple logo of the camstudio. It can be downloaded here: http://victor.westmann.googlepages.com/camstudio-logo.zip
Its a very simples .SVG file and the same image in .PNG format. I hope it helps. Cheers.
