Mesh Morphing in WPF - Pixel-in-GeneMorphing of 3D meshes can be very cool to play with. I am sure many of
you must have seen this in action in movies / tv or even CAD like
programs. Its a technique where a set of vertices that describe a 3D
mesh change their positions over a period of time into a new surface. In
the figure below you can see a Plane mesh morphing into a Sphere. The
interesting thing to note here is that only the vertices are changing
their positions while keeping the TriangleIndices and TextureCoordinates
the same. In some cases you may also want to change the Normals if you
have specific lighting requirements. Otherwise you are in good shape
just manipulating mesh positions.

the Continuous Client -- Engadget
There is a missing link in our computing experience that has recently been made painfully clear thanks to the current onslaught of highly advanced mobile devices, and I believe the solution to this problem is simple. Allow me to set the stage. Just now, I was reading one of my favorite blogs on my laptop, but I wanted to relocate to my couch, and I wanted to switch to reading on my iPad. Of course, this required starting a new browser session, calling up the web page, and finding my place once again. This same situation now occurs constantly with Twitter (where I'll have to read and re-read timelines depending on whether I'm checking on my phone, laptop, or iPad), Facebook (a mess similar to that of Twitter), and even in my IM sessions (different locations, different conversations, different logs). There is no continuity in my call logs, text messages, or notes when seated with my laptop or desktop, and there is no way in which to continue working on something in an application on two platforms without tremendous effort. Frankly, it's a mess.
