@fjFrédéric Jacobs ha, and a MEMS element that was planned to contain 15000 holes, where each individual hole had two sides of a capacitor around, one connected to a light diode, to which a glass was connected. This would then bundle into the „fiber tree“ that went to the FPGA rack.

You had to use light because you can‘t use electricity when you‘re soothing electrons at this MEMS element. Once the beam went through these holes, you could control every single hole individually whether it would deflect or not.
