I'm thinking of designing the Orion spaceraft as a paper model, despite the occasional plastic model I've seen. Paper is my medium. First of all, before I commit myself to this project, two questions: 1. Does anyone know of a model of the Orion nuclear pulse rocket that has already been designed? 2. If not, where is a good source for concept drawings of the vehicle? I have always wanted to build an Orion for myself, but now I'd rather offer it for free as a download when (and if) I am able to draw it. Any help on this would be appreciated, and if there's any interest out there in building this, let me know!
