Here, too, Karl is an autodidact creating striking images full of symbolism and story lines. Next to the traditional editing, Karl now uses real life model photography with mixed media and CGI edits for background and theme.
Per 2026 Karl is also an Ai/CGI producer and advisor.
NOTE:
Regarding the book *Codebrekers* / *Hunt for the Nazi Gold* and the subsequent reward for cracking the code:
In the late summer of 2015, Karl Hammer received a promising tip from Germany. A member of a family living in Mittenwald told him that one of the older relatives had once mentioned the existence of a hiding place for Hitler's diamonds. However, no gold was said to have been hidden there. Karl spoke with the family under strict guarantees of anonymity; for understandable reasons, they did not wish to become involved with the Nazi past, a subject that remains an emotional hornet's nest. The information Karl received pointed to a location near the old Mittenwald railway line—a section of which indeed dates back to the Nazi era. Others, including Mr. Cyril Whistler (whose name may be disclosed), were also pursuing a lead in that direction. This meant that the code within the 'Marsch Impromptu' had been cracked, allowing the book to be withdrawn from sale and the reward to be cancelled as per 2016.
