Green Building

Try reading binary letters off the lowest level of the Green Building lights.


If this is Tetris, then perhaps each button displays a Tetris board. If that's true, then "clearing the board" seems like a good thing to do -- but how do we do that? What pieces do we need to clear the board? What pieces do we have?

Each answer contains Tetris pieces notated with the letters I, J, L, O, S, T, and Z. For example, "HELLO" contains the pieces "LLO". For each answer, figure out the Tetris pieces contained within. Which board can you clear with these pieces?


To extract, simply re-order the first letters of the answers by the order of the switches they match up to.
