"Yes I play TETRIS, how did you know?"
Here's my entry for the TARDIS of the Week (no theme)! The architecture of this interior is really simple, just a main room and a lower level; The uniqueness comes from the design and the colours.
I used two different types of roundels for the main room, but the main thing you notice is the TETRIS blocks on top of each other on the Walls and on a bit of the roof. I put some coloured glass on the ground with light under it and I also did an epic TETRIS game on the chalkboard because it looks cool.
You can join the lower level by taking the stairs which are TETRIS blocks used as platforms, this is the room that looks more like an actual TARDIS with two other sets of roundels. I placed library blocs (books are cool) and a wooden monitor that shows which piece is dropping next. There are 4 pillars made of TETRIS blocks in the Walls. You can see the white lights on the roof and terracotta blocks on the ground, and that's right, both of these elements are in the shape of TETRIS blocks (who could have guessed)!
I like TETRIS.
