So far all of they holy grails of ID have been shown that they could evolve.
First there was the flagella, and it was shown to be just rearranged parts that had other functions in the cell.
The eye was shown how it could evolve from just light receptive cells into an eye.
Even the Blood clotting system was shown that it could evolve and that the intermediate steps would have a positive effect on the organism.
The IC folks have not yet shown a single part that could not be broken down into useful parts.
As for matter from energy. All you have to do is a little math. E = MC^2. Now we the math. M = E/C^2. Tada, matter from energy.
