In the past I've shown off this great program for working with tablets or with a Wiimote whiteboard called Uniboard. The problem was that Uniboard seemed to be dead. There had been no updates or tweets for months (maybe a year). I figured it was a piece of great software that would just fade into non-existence.
Well, yesterday I went looking for it again. I had observed a colleague of mine teaching yesterday and realized that even though it wasn't being updated that he could definitely use it. Well, apparently last week Uniboard went Open Source. It is now called Sankore and is totally free. Warning, the page is all in French. Here's a direct link to the download page.
The free version used to have a nag-screen on every page, it's gone now. The screen-capture tool had a watermark in the recording which is also now gone. I can whole heartedly recommend this program. Whether you need a tool to help present lessons in class or you want to record lessons for reverse lecture you should check out Sankore.
