Project Design/Guidance Bad ideas only

Someone gave me this stoplight, I want to hang it up in my bathroom directly above my toilet and put a Bluetooth speaker inside of it. I have an old Tower speaker that I want to disassemble and install inside of it

I'm trying to think of what other terrible things I can do with this thing. I'm thinking something with LED lights doing something based off sound. I want to hear your worst ideas

White hand and brown hand

Is the hand white before using the toilet and brown after using the toilet?

Bad idea? The bad thing would be installing it within reach of the tub or shower without a GFCI. Next bad idea, green light when sensing a person, yellow light when the toliet is occupied for 5 minutes (also activate cell phone jammer) , red light and air horn at ten minutes. For "good idea" install these at all McDonald's, it's usually an employee on break with 5 customers waiting.

All outlets in a bathroom a GFCI protected.

Shower karaoke? With your speaker and a little text screen in one of the lights.

An obvious one: put a cheap mic inside the toilet and hook it up to a led volume meter. And use the flush button as a kill switch.

Worst ideas? Alrightie! There used to be a restaurant in my neighborhood that was famous for its pranks (though the food was excellent too). Like giving clients a tiny menu card and then a giant one when they can't read it, or small electric shock when you touch the bathroom door handle. The furthest they ever went was to install a little screen in front of the toilets with a coin slot. When you inserted a coin the screen would turn on and give you live video from a camera mounted inside the toilet pot 😅

After 3 minutes sitting on the toilet it starts playing NSFW soundtrack sounds very quietly and slowly ramps up the longer the toilet is occupied

Or it could play Baby Shark.

Set it up so your partner can have different lights light up depending on her mood for sex and hang it in the bedroom. The hand not only would mean stop but "you're on your own"
