More of a tech demo, really… Let me know what you think anyway!
The 4th level may or may not be impossible.
Drop the big panel.
Click the sockets to move the wires.
There are some hints in the first comment, although 'discovering how everything works' could (should??) be seen as part of the 'Start With Nothing' theme (besides the 'no controls').
Disclaimer: It's probably not a good idea to remove wires from sockets with a screwdriver in real life.
