TetriNet Rotation System

The PC based multiplayer game Tetrinet uses its own rotation system based on that of Tengen's game. Tetriminos spawn with a random initial rotaiotn, below the ceiling, in the center (rounded to the right if needed).
== Basic rotation ==
The tetriminos rotate as shown in the picture. I, S and Z alternate between two different states. The logic behind the uncommon and somewhat irregular behavior of J, L and T could be that all rotations of all tetriminos are placed top left in the bounding box (with the exception of I).
== Wall kicks ==
Tetriminos can kick out from the walls of the playfield but not from walls of blocks. There are no floor kicks.
