Very good question, Brother Kenneth.

Having gone through all of Dave's Bordered Characters (BC)code, I can say that
he could - and would - move a mountain using only a teaspoon.  However, I think
all of that is pretty complicated and would require a full reworking of the BC
code to pull off.

So, I'm gonna guess that it's a very skillfully applied transform matrix.
