The oldest way of voting, now digitalized by Twebcast. Just raise your hand (holding your phone) and your screen will turn green and you have voted YES. Flip it, your screen turns red and you vote NO. This has worked for thousands of years and still works like a charm. Extra cool in a live audience where everyone physically can view the result in the room. Even more efficiant in a dark room and also works perfect filmed in a stream. If you aren't one of the lucky ones in the room you can of course participate and vote from your computer at home. Luckily you don’t need to flip your computer since it will be a normal poll with options.
