Components of the Graffiti Jumble
Grid: The grid of squares are made up of equally sized pieces of wood with magnets attached on one side and a flat surface on the other. The surface provides a blank, movable palette for art to build up over time. Once the surface is painted, pasted or stickered with something, the squares can be rearranged to produce a new canvas. The next person to add to the surface can change his or her palette, while providing a new background for the next artist to tag.
Frame: The frame sets the boundaries of the grid and prevents the magnetic squares from sliding down the wall's surface. (Even strong magnets slide easily.) The frame will be bolted or screwed to the wall.
Magnetic Surface: A magnetic paint undercoat provides the surface to which the magnetic squares will stick. Since large iron structures are rare in most urban areas, any surface can be made magnetic with the use of magnetic paint. Once you choose your location, you will have to paint the surface 3-4 times before attaching your frame and squares on top of it.

Just be discriminating when you pick up street wood! It can have embedded hardware which can be extremely dangerous and cause injury when cutting on machines.
Materials List
Plywood
Amount: Approximately 9 Square Feet
Cost: Free, off the street.
MDF
Amount: Four strips between 2 and 4 feet long, 3/4" inch to 1 1/2 " inch wide.
Cost: Free, off the street.
Magnets
Disk Magnets: 3/8" inch x 1/8" inch NdFeB Disc Magnet, Ni-Cu-Ni plated Reccomended
Amount: Approximately 100
The number of magnets you need depends on the weight of the material you are using and the strength of your magnet. I used four 3/8" x 1/8" magnets on my 7" x 7"squares of 1/2" inch thick Plywood. You may need more or larger magnets for thicker/heavier materials.
Cost: $20

Magnetic Sheets
Amount: Approximately 9 square feet
The amount you need depends on the overall surface area of your squares. Magnetic sheeting does not have as strong of a force as NdFeB magnetic disks and may not work as well for thicker/heavier materials. I'm suggesting this as an alternative method for those who may not have access to all of the tools necessary for attaching the magnetic disks and have not modeled a version using this material myself.
Cost: $5 per 24" inch x 12" inch sheet
