There is and old Visualization in Mathematica that
gives a modulo 2 version of a Pascal's triangle.
It is a right angle version of a tetrahedral 3d Sierpiski triangle.
Here it is: ( copyright Mathematica):

g=Flatten[Table[If 
Mod[Multinomial[x,y,x],2]==1,Cuboid[1.2*{x,y,-z}}],{}],{x,0,15},{y.0,15},{z,0,15}]
Show[Graphics3D[g]]
