  Scanning tunneling microscopy (STM) images are obtained for the first time on
few layer and twisted multilayer epitaxial graphene states synthesized on n+
6H-SiC a-plane non-polar surface. The twisted graphene is determined to have a
rotation angle of 5.4{\deg} between the top two layers, by comparing moir\'e
patterns from stick and ball models of bilayer graphene to experimentally
obtained images. Furthermore, the experimental moir\'e pattern shows dynamic
behavior, continuously shuffling between two stable surface arrangements one
bond length apart. The moir\'e pattern shifts by more than 1 nm, making it easy
to observe with STM. Explanation of this dynamic behavior is attributed to
electrostatic interactions between the STM tip and the graphene sample.
