Right now this thing is taking up more than a quarter of our living space...your guess is as good as mine! Actually, I do know what it is...it's some kind of contraption to project images onto and then draw or paint onto glass to add to the image- like an analogue photoshop layering system if you will! The accordian is just to throw you off! Ha! Actually, that is another project...sigh...now how to get into those cabinets?
