So I wanted to do this for several reasons.

For one I have a Tetris clone on my computer called NullpoMino. In it there is a mode called Speed Mania 2 which mimics Tetris the Grandmaster Deluxe 3's Shirase mode, the fasted officially release version of Tetris out there. In the final 3 levels all the Tetraminos become black and made of two green brackets. [ ] Turns out this is a reference to WAY back when Alexey Pajitnov made Tetris on an Electronika 60 Computer. I added some things to make it more like the whole thing is a Shirase look with time, level, hold and next displays.

Yeah it's nothing fancy but I like Tetris enough to make this.

This video shows some of the original Tetris as well:
