That's true — there are certainly a lot of variety now, especially with 3D printing and garage kits. The "long tail" has definitely been kind to the esoteric modeler.

Adult-me recently took to designing a kit for a NASA "Space Tug" that never existed (only proposed "artist's renderings" from the 1970;s) [1]. It is so esoteric that no one made a kit for it — I had to learn to use Blender, ha ha.

I just wish more kids were into modeling.
