Step 1: Find some stuff!
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
Some markers or paint
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.)
Step 3: Measure, Mark, and Cut
Step 4: Gluuuuuuuuuue!
Once you're satisfied with the layout, heat up your gluegun and get cracking!
Step 5: Make it purdy!
I used markers to color the cork once it was glued into place. I like the kind of "Stain" effect that the markers have on the cork. Some markers may work better than others. I used hiliters. Your mileage may vary.
Step 6: Cutcutcutcutcutcutcut
I left a little posterboard around each piece for a big of a matte effect. You can choose to cut out the corner nibs or leave them -- I cut mine out.
Step 8: Attach magnets and enjoy!
Now you can tetris!
Go get yourself some tetris music and build this thing for the full experience.
