Tarot cards.

Sean reminded me, sometimes I use my monitor as a TV (to view DirecTV through Chromecast from my phone, or to play with the Switch or the PS3), if that counts. Also I have one of those spikes people put in their yard to keep people from driving on it, it's semi-transparent and has a cavity in the middle, I keep it in my room and I used to put a light bulb in the middle to light it up. But I didn't buy it, I stole it from someone's yard a long time ago. =P

Probably some kitchen gadget? The only thing I can think of is a coffee bean grinder that I use to grind spices instead, but I guess I'm still grinding things, oh or I use a TV as a PC monitor?

I baught a tablecloth when I first got here. It's not a very different use case but I usually spread it on the floor to eat lunch/dinner on it like I'm on a picnic or something!

I have a French press for coffee and I use it for tea making. All the time.

Wireless earbuds. It's collecting dust in my desk.

I bought a shelf for my entertainment center. I didn't buy the right size so I cut it. Then I cut it too short so I hung it on the wall. Now it's a wall shelf. So its still a shelf but not the right shelf😁
