That's a Fotoconic turntable - link here: Fotoconic White Electric Motorized Rotating Turntable , about $39
But you could also find a battery-operated lazy susan for less $ to avoid cords.
I found this one, not sure if it's the same one but looks like it
I feel like a smaller one would look better. Maybe an 8" version
The rotating base plugs into the wall and besides it being clunky, i can only connect to the wall to rotate while the glass door is open. I am at a loss as to provide power while it is enclosed and does not look ugly. Also, Billy is supposed to get here tomorrow. Hopefully...
