What would the process be to do something like this? I was planning on putting thin cement board over the existing brick and up to the ceiling. Then do the same thing with the brick on the bottom and cover some of the hardwood with the cement board as well. Would that work?
I started building my own app to do with but before I go too far, I'm wondering if there is already something that does this. Essentially I want to be able to set up my phone DTL, then it would automatically detect any swing and display it on a TV mounted on my wall, ideally with the plane lines drawn. I've seen similar things in professional coaching studios, but haven't found anything for home use
