Last of the sewer level pix, I swear.
The finishing touch on the third floor is an array of randomly flickering lights in the ceiling.
Three concentric redstone repeater circles make a random signal generator. The rest of it is to take the signal to the lights.
When I finally moved on to build the next chamber, an asshat mob went and stepped on the triggering pressure plate, and damn near killed my computer. I’ve stopped all the circuitry, but I have to fix the dang doors in the startup area on the bottom floor.
I’ve got the fog set to “Tiny”, the graphics to “Fast” and everything that could make my poor computer wheeze turned down or completely off. And I *STILL* have framerate issues.
Not helped by my computer spontaneously turning itself off at random moments. Ugh.
