Interesting thingy, looking complex and nice.
How do I test it though? Do I have to insert items? Where do they go out? Do I have to power it? Where?

If you want to showcase this machine running neat and swiftly, make it easy for us to test it and provide good instructions to do so.

For rankups, we test overall skills and creation building ability, thus a single part of a machine (display) is nice, but not enough. Please build a big machine using your display, preferably Connect 4, if it is made for that.

Nice tinkering though, now make it great and PR again :)
