I also greatly enjoyed the Iron Man movie series which has shown through in some of my projects. Shown below is a custom laser cut Iron Man War Machine arc reactor I designed and produced. I’m thinking about making another one and then making a set of headphones from them!

Besides this I made an electromagnetic hand repulsor designed to fit on you palm so that you can launch metal objects! I need to redesign it but it was able to shoot a magnet a yard or so.
