Here is a review of the ARpiCADE I wrote back in 2018.  It includes a number of photos,  videos,  and might be a good place for folks new to ARpiCADE to start researching what it can do for you... just keep in mind the review is based on the Pi3 version.  There has already been a Pi4 and now a Pi5 version of the software available so things have only gotten better/faster/stronger...
