Hi @snwh
This one doesn't feel controversial - happy to fork/PR if you want it - it's just a recognisable Tetris piece, drawn at the different sizes.
Based on screenshots, I think I've honoured the colour of the specific piece and the in-game background, but I've used Suru substitutes. The "black" is from Terminal, and the yellow is a gradient of two shades from the Suru palette.


How do you feel about this one...?
