Over in the OpenScience Forums there are two threads which ask some good questions:
- gelinp asks if there are any open source graphics programs that allow the user to draw curves on a 2-d canvas and then place tangents and other geometric objects on the curve at selected points.
- Lailai has an interesting idea inspired by this article in Nature for an online international conference (including presentations, discussions and interactions).
Stop by the forums and have your say!
