Sun used to say “the network is the computer”.
Now you are telling me we could potentially have “the DVD is the computer”. Imagine printing not just a capacitor but a whole PCB and soldered components, putting the innards of like a Raspberry Pi on top of a specially crafted DVD that has said single-board on one side and a readable DVD surface on the opposite side! :D
there was an inkjet printer that had a special tray for CD/DVDs
the intent was to add artwork to the discs, but if you put a copper-plated board in there, printed on a circuit board, and etched away the area left behind, you'd be almost there :)
drilling holes and thru plating is my least favorite step tho
