The idea behind this lamp is quite simple, really. If you are getting ‘ideas’ and want to communicate this with your partner non-verbally, you can simply switch this lamp on. If your partner leaves the lamp on, it may be a GO. If the lamp is turned off, maybe a neck rub will suffice. The base is a beautiful piece of purpleheart hardwood. The top socket I’ve added has a dimmer switch. I also just thought it looked more cool! These are NOT brass balls! I’m not sure what the metal is.
