The other project I'm aware of so far is I could make an airfoil with foam by cutting using a NiChrome wire foam cutter. The way this works is the wire gets a certain amount of electricity passed through it to heat it up and melt the foam.
A lot of Swift's processes remind me of school. The way they go about solving problems is very similar, and they also reflect on what they could do better next time and what works well.
I can tell that Swift is all about taking ideas and making them come to life. They generally get some idea of what they want to build and then they come up with the process for building it.
