Here are some typical microscope images (showing a surface, which has been shaped using a power beam).

First surfi-sculpt object
Second surfi-sculpt object

Using a focus-stack one can compute images with extended depth of focus:

Extended depth of view for first object
Extended depth of view for second object

If the surface can be illuminated properly, one can even do a 3D-reconstruction of the surface:

3D reconstruction of first object (742kB video)
3D reconstruction of second object (725kB video)
Stereo picture of first object (2.2MB video)

As the idea for the algorithm was fixed already, it was possible to implement the algorithm as a command-line tool in less than 4 days, using existing Mimas-software (exspecially the operators for boost::multi_array).

As this is a "quick hack", there's still lots of space for improvements.
