The Description:

Hello there! This is NOT a puzzle. It IS possible to create all sorts of logic gates. The OR gate itself can be made with 3 components, inside one single "unit" of space!

Various rooms with examples of logic stuff. Including:

OR buttons.
LATCH buttons.
ON-OFF buttons.
A JK Flip Flop,
An OSCILATOR.
A DELAY/timer. (nice for bridges)

More to come! please comment.
