The goal is to do [something like this](http://www.cubebreaker.com/do-it-yourself-wall-art-seven-samurai-in-your-home/) — project some art on the wall, and paint that art onto the wall. The thing is, I'm much better at digital art than I am at freehanding art, so projector art makes sense for me. * There are [art projectors](https://www.artograph.com/projectors/tracer/), but they're very low end. * Do I need 1080p or 720p? Look [here](https://docs.google.com/spreadsheets/d/19CRKYlIt7ZCfg0slvkHtED8Gq4xqqHZn6RF8TdCidF4) for a comparison of 720p and 1080p projectors. ## Notes * [USE THIS TOOL](https://github.com/qurn/xrandr-keystone-helper) to do keystone correction under Linux
