We have all seen stuff like this, but these tables often cost a lot and large touchscreens aren't cheap either.
I'm wondering if I could use something like a touch frame (https://www.amazon.com/Chengying-Points-Multi-Touch-Infrared-Touch/dp/B07RQH8BT4) and a ceiling mounted projector to emulate the experience.
Do you guys think it's a dumb idea?
