On this screen you can create a spirograph, which can be used as a block 
pattern. 

The designs are limited to patterns that become closed over one full 
circle. 

<b>Number Of Loops
Set the number of loops along one full circle.

<b>Spread
This setting determines the size of the hollow inner circle of the pattern.

<b>Flip
You can flip the loops inside or outside of the circle.

Touching the [Random] button will set random numbers for all the 
settings.
