When I saw the Fridge Magnet Contest, I thought to myself, "There's something I can do!" Sweet and simple. I immediately thought of Tetranitrate's awesome Tetris Ice Cubes. Tetris would make some great fridge magnets!

Step 1: Find some stuff!

So you are probably thinking to yourself about now, "Hey, didn't distortedlabs just do this???"
That is absolutely right. I had a hard time finding magnets, so give me a break. For the record, I found them in Ace Hardware, near the hammers (???).

Here's what you'll need:
Some posterboard (or some other kind of stiff backing)
A roll of gasket cork (or something similar)
Hot glue gun
Scissors
A ruler
Some markers or paint
Magnets!

As you may have noticed, I'm pretty ambiguous here in the materials. This stuff works, but you might find something better. As for the magnets, I found a roll of adhesive magnet, which works nicely.

Step 2: Make an Action Sequence Schematic (A.S.S.)

You'll want to do a little planning to see how things will come together. I only had a strip of posterboard, so I wouldn't be using the super fancy maximum efficiency design to lay the squares out. I decided to go with two inch squares to blow the competition out of the water.

Step 3: Measure, Mark, and Cut

Now that you know what you're doing, go ahead and measure out your squares. I decided to use 2" squares because my cork was 12" wide. Mark out your grid, and then cut out the squares. Once all the squares are cut out, you'll want to cut off the corners. I made a little template so they would all be uniform, but it's probably just as well to eyeball it.

I got all the materials at the hardware store. You might want to ask an employee, as most of this stuff is kind of obscure in a hardware store. The magnet comes in a roll, one side is sticky. My other option, which I didn't wind up using as I found the magnet tape was to go to the dollar store, buy a bunch of crappy magnets, and rip the fronts off of them to get at the plain magnet.

I'm expecting some of these for Christmas -- but I want the right colors and shapes - don't skimp on the posterboard!

Wow, people are totally taking off on the Tetris Theme :) I'm not complaining -- I think it's cool )
Great idea with the cork board on top of the magnets. I guess if they were thick enough you could use a couple push pins and double up on the holding factor of the magnet.

Oooo, I like that. I was thinking about doing multiple layers, but I was concerned it wouldn't come out looking as nice. Really ideally it would be done with wood blocks like Tetranitrate's mold positive.
