I think it would be awesome to make sculptural work.

I spent much of my childhood not actually playing with toys but posing them. G.I. Joes, plastic cars, Barbies, tissue boxes, anything I could get my hands on would end up displayed in gigantic battles and slice-of-life comedies on my bedroom desk. I'd always leave them posed that way for a couple days since the work to get them upright and undisturbed took hours, but after that I'd disassemble them and making something new. Funnily, I've never stopped thinking of my work in terms of a 3d playset despite working on two-dimensional surfaces; my priority is still to pose the characters in ways that communicate their relationships to each other and also tell a story while showing off a fabricated location.

So for sculptural work, either I could go the toy route and make little fantasy-themed dioramas filled with movable characters, or I could do the same thing in life-size, with viewers able to walk through the setting with its individual sculptures (characters caught up in the overarching narrative of the scene, interacting with each other and their surroundings). The sculptures would be colorful and cartoony, with stylized painted backgrounds and props.

As one example of the type of stuff I'd do, I could fabricate a hole in a gallery wall that would have an enormous eye peeking into a brightly colored living room with plaster painted furniture. Freestanding characters would be recoiling in fear, dropping household items and bolting towards the exit. I'd like viewers to walk through and examine little details of the setup while just appreciating the humor of the narrative and being a part of its space. In a sense, working in 3d would more easily fulfill my goal of engaging viewers in the entertaining aspects of artwork.
