Fascinations makes these awesome Metal Earth 3D model kits, including ones like this Iron Man model that is printed in color (most of their models, however, are monochrome steel).
Each model consists of one or more laser cut sheets of steel. Pop out the individual pieces from the sheet, bend the tabs using pliers, and then assemble.
Whenever I think to myself “I can’t possibly understand why people watch any of the various Stargate shows” I stop and remind myself that I am still a devoted fan of Voyage to the Bottom of the Sea which makes Stargate SG1 positively Shakespearean in comparison. Still, for some reason, I still find it engaging even with the silliness and absurdity.
I’ve never been much into plastic models, but this Flying Sub model kit looks pretty sweet. Of course if I put it together it would look nothing like this, but at least I can dream.
