If I saw that, I'd assume something crazy is happening to the GI and do the owner a favor by turning it off.
Even if I knew it was "normal," I'd hate to be playing the machine next to it. One of my least favorite pinball features of all time, the Data East era GI relay flicker, gone back in time to infect EM games. Even the sound of it is annoying.
All that said, great work and clever implementation. Just not for me.
