Taking tetris into the real world and onto the fridge.
This is for the one week fridge magnet challenge.
Took about 1 hour.

Step 1: Get Materials

For this project I used: one 1' by 1' square piece of adhesive back magnet sheet
graph paper
old magazines
sharp razor blade
scissors

I got the magnet sheet at Princess Auto (Canadian tool store) for 10 bucks. It is 1.5 mm thick and has an adhesive backing on one side.

Step 2: Draw Out Tetrominos

Get your graph paper and draw out the tetris pieces (tetrominos) onto it. Each tetromino is made up of four squares arranged in different shapes. You know the shapes but here they are again... Stick, J, L, S,Z,T and Square. http://en.wikipedia.org/wiki/Tetromino

My squares were all 1/4" square. I made a square 6" square and tried to get as many of each shape onto the grid paper with out wasting space. My pattern worked but I am sure there are more combinations of ways to get the tetrominos on the page.

Step 3: Glue Grid to Magnet

I used a regular glue stick to glue the grid paper to the non adhesive side of the magnet sheet. Make sure to cover the entire surface of the grid paper with glue as it will be much easier to cut out the shapes. Using a glue stick makes the grid paper easy to remove after the shapes are cut.

Step 4: Cut, Cut, Cut

Using the razor and scissors cut out all the shapes in the grid. Once they are cut you can remove the grid paper glued to the one side

Step 5: Add Colour

Take an old magazine and find a page on which there is a large area of a similar colour or pattern. Each set of shapes should be a different colour. Take the paper off the adhesive side of the magnets and place them on the opposite side of the magazine page. Cut the paper around the outside of the tetromino. The magnet is finished. Again, there are probably easier/more creative ways to add colour to the shapes, I chose magazines as I had some lying around and it was easy.

Step 6: Go Tetris

Throw the magnets up on the fridge and begin playing with 'em. This project took about one hour to complete and cost about ten bucks. Not bad for a quick weekend project.
