I really like playing with papercraft – it doesn’t cost much to make projects, and they can be incredibly complex and interesting. Paper Forest posted about this wonderful spinning star – I’ve watched this video over and over, trying to figure out the movement and why it’s so elegant. They say the original design is by Ramin Razani, and there are directions to make a similar cutout here.
