Here's a tetromino quilt my mum made for me for my birthday a few weeks ago. I told her I wanted something different so it wouldn't be too plain looking, and wow, I don't think any two minos are the same.
i can tell she's played some tetris. that's some nice 7-bag quilting, with an I piece on the way, and SRS colors to fit the randomizer. most people wouldn't be able to create a design like that. maybe she had some help...
Heh, heh, yeah, I had to help her with the piece layout. She doesn't really play Tetris, but I did get her to play it on the Gameboy once, and she went and played on Tetris Friends when she started making the quilt.
