If you’re into video games and you’re into shelves, you’ve probably run across these in one form or another.

The problem? These (the unpainted ones) are $700.

These, with the colored backings, are $1,300. Plus shipping. Or, I believe you can order them for $120 per block. For the record, for $120 you can easily buy a non-functioning Tetris arcade cabinet and just store stuff inside it.

Instructables has instructions on how to build your own Tetris shelves. I’ve never tried it, but it looks like a lot of right angles to me. I can’t imagine they would be that difficult to crank out. If you build some, I would love to see them!

If you are broke, untalented, and/or lazy, you’ll have to settle for these: Tetris Ice Cubes.
