Tupper's Self-Referential Formula
J. Tupper concocted the amazing formula

where 
is the floor
function and 
is the
mod function, which, when graphed over 
and 
with
 |
gives the self-referential "plot" illustrated above.
Tupper's formula can be generalized to other desired outcomes. For example, L. Garron (pers. comm.) has constructed generalizations for 
to 29.
