The save fileThe Thumbnail (For some reason is bigger than the .bls file)And I just made a new one, its compacted.

It uses a simple control panel to send functions to the circuits.

The cover contains numerous stacked circuits to perform operations.

The functions exit the box and finish the circuits to create a blue light over the sum.

I spent three hours on this because Instead of using Prebuilt Adders and Full Adders I tried to make it as small as possible and connect the stacks somehow.
It was fun to make, but it got boring after. Any suggestions to make?
