Libre graphics is an open source software established in 2006. Richard stall man conceptualized four ideas as far as 'open design' is concerned that centered around using, copying, manipulating and distributing software. Manipulation and distribution of original work brings to the surface issues regarding licensing and copyrightsIn this context, remix culture promotes integration and manipulation of original work to create new information.

Experimentation and manipulation of original codes to form new and "remixed" versions of the original sketch.

House experiment
Image(right) aim: create a house drawing a circle, square, rectangle, triangle.
Image(left) Codes for the color, placement and axis of the shapes.

Shapes placed by calculating numerical value of first shape and adding it to next shape.
rect: 20, 0, 100, 500
rect2: 120, 0, 100, 500

Images showing recreation of display examples by manipulating original sketch codes alongside the changed codes next to the image.

Original image and manipulated image.
Achieved by altering ellipse size and placement on X and Y axis

Addition of space between the altered/expanded size of ellipse and changing of background fill color from 0 to 100

Alteration of space between horizontal shapes.

Alteration of rectangles and ellipses to vertical and horizontal lines by expanding them to 300. Increase of spaces gives the desired visual look

Background alteration to 0

Background alteration to RGB= 10, 10, 100

Use of Mathematical addition in placing the objects next to each other eases the process of having to 'run' the program multiple times to test the correct position of the object.

For example:
If a rectangle of width 20 is placed on the X axis at 70, the next rectangle will automatically be placed on the X axis at 90(20+70).

Online tutorials on hello processing are a good learning source.
