Orchestral Marble Machine

Here's something a bit different to brighten your day. It's an acoustic instrument that's powered by nothing more than a crank handle and some levers. That's right, there is nothing electronic about it. Strange, blogging about this on a website which has 'electronics' in its name, but it is simply too awesome not to share. This incredible projects, posted by Youtuber Wintergatan is a perfect example of engineering and creativity coming together to make something awesome, an instrument that makes sounds using marbles and gravity.

What's mind blowing is that it's made mostly out of wood! Now think of the possibilities of something like this controlled by an Arduino. You could write symphonies with the thing.
