Finished up the paint and wall graphics on the arcade room this weekend; it looks something like this now:

Also ripped out the last of the heinous chandeliers in the living room and replaced it with some cable lighting. Unfortunately, it turns out that the combination of low voltage magnetic dimmer, magnetic transformer, and the MR16 fixtures I got makes for a very... buzzing experience. The filaments themselves buzz when they are being dimmed due to inrush currents from the PWM-esque power signal coming from the dimmer. Haven't figured out to solve this yet; apparently you can just put a choke on the power line and that'll solve it, though there doesn't seem to be a consensus on the internet regarding this. Anyway, for now I have lights that buzz when they're at any brightness other than zero. Great.
