Over the past week, I have not been able to get this music out of my head, or stop thinking about how clever and impressive this machine is.

Swedish musician Wintergatan spent more than a year hand-building and crafting this machine in his workshop.

It’s made of over 3000 pieces, constructed out of nothing but plywood, screws, wire, marbles, pieces of instruments and LEGO (the trademark sign of any creative project).

Just watch the video above to see it in action. If you’re anything like me, you’ll have to watch it again right away.

It might be shaky, ugly, and have a dance-music style which not everyone will like. But damn is it impressive.

Check out this behind-the-scenes video showing the build process. If you look at it step-by-step, you might see that anyone could create something of this scale if you just follow through on your imagination, and are willing to adjust the design partway through.

If you were as impressed with the machine as I was, then please share this page, and let us know what you thought in the comments below.
