Bsurfaces is a modeling and retopology tool which combines the use of freehand strokes, bezier curves or loose edges to generate polygonal surfaces. It can be included in a traditional polygonal and subdivision modeling workflow, speeding it up substantially.
Bsurfaces is a Blender add-on, it can be used to build both open and closed shapes, extrude selections, bridge between two selections, having full control over the shape, direction, and twisting of the final surface. The output is a clean topology composed of quadrilateral faces. Triangles are also possible when building surfaces using crossing strokes.
The different options can be modified interactively, allowing to see how they affect the resulting surface in real-time.

After a few tests I thought it's time for a first tutorial on how to use the new Blender tracker, that is being developed by Sergey Sharybin during the 2011 Google Summer of Code. Currently the tracker is only available in custom development builds of the so-called tomato-branch.
(grab one here: http://graphicall.org/gsoc)
I am pretty sure that it will still change a lot, but it is already totally usable.
There are endless scenarios where you can use a 2d tracker, with 4 corner pinning being one of the most obvious ones.
But you can also do image stabilizations for shaky footage as well!
Francois Tarlier will most likely publish a tutorial on that.
I also have to give huge credits for the guys who developed libmv, which is used for the actual tracking algorithms. So thank you Keir, jmichot and MatthiasF!!
Tutorial of 2D stabilization using the new 2D tracking feature in Blender.
This is feature is part of GSOC 2011 developed by Sergey Sharybin who did a wonderful job already.
Thanks to Troy & Sebastian for their help on this one as well as for the footage
Sebastian already did a tutorial on Corner Pin as well here : vimeo.com/25516157
Stay tune since I'll release some python script which will make all those teadious work much much simpler
