A moire pattern is a superlattice(superpatern?) formed when overlaying similar patternson top of one another. The step of a new pattern is larger than or same as that of any of the original structures. This is related to the concept of least common multiple. Consider two patterns with step 2 and 3. Upon overlaying the two structures, a new pattern with a step of lcm(2,3)=6, will appe.. The Nothing Grinder(aka. The Trammel of Archimedes) A nothing grinder, aka the Trammel of Archimedes is an elipsograph; a tool for drawing elipses. In the gif file above, the shaft is moved in such a way that the end part outside the rectangular area trails an elipse. Proof) segment AP= a(long radius), segment BP= b(short radius), line PXY is perpendicular to line BX, AX when angle(PBX)= t, angle(PAY)= t segment PX= b*sin(t) segment AY= a*cos(t) ..
