What to do with this 'mystery machine' to turn it into an sci-fi monitor/screen/prop that's alive? Ideally, stand-alone?
As I say in the question, I'm looking to turn it into an sci-fi monitor/screen/prop that's 'alive' somehow; continually generating interesting content. What I'm thinking of is replacing the big, central meter with a monitor/screen of somesort. But, what kind? Ideally, this'll be easy to make, stand-alone and cheap.
