## These Beautiful Images Are Created by Drawing Squares

In order to create beautiful images by drawing squares, it is very useful to use

**16,000 Squares (3)**

This image shows 16,000 squares. For each k=1, 2, 3, … , 16000 the vertices of the k-th square are:

(X(k)-A(k), Y(k)-A(k)),

(X(k)+A(k), Y(k)-A(k)),

(X(k)+A(k), Y(k)+A(k)),

(X(k)-A(k), Y(k)+A(k)),

where

X(k)=sin(10πk/16000)(cos(18πk/16000))^{2},

Y(k)=(cos(14πk/16000))^{3},

A(k)=(1/400)+(1/25)(cos(64πk/16000)cos(192πk/16000))^{12}+(1/70)(cos(192πk/16000)cos(384πk/16000))^{10}+(1/120)(cos(384πk/16000)cos(1152πk/16000))^{10}.

**16,000 Squares (4)**

This image shows 16,000 squares. For each k=1, 2, 3, … , 16000 the vertices of the k-th square are:

(X(k)-A(k), Y(k)-A(k)),

(X(k)+A(k), Y(k)-A(k)),

(X(k)+A(k), Y(k)+A(k)),

(X(k)-A(k), Y(k)+A(k)),

where

X(k)=sin(10πk/16000)(cos(14πk/16000))^{2},

Y(k)=cos(14πk/16000)(cos(10πk/16000))^{2},

A(k)=(1/400)+(1/12)(cos(14πk/16000)cos(42πk/16000))^{12}+(1/30)(cos(96πk/16000)cos(192πk/16000))^{12}+(1/60)(cos(192πk/16000)cos(384πk/16000))^{10}.
