My prompt was:

Imagine you have to draw a SVG of an object. As a model that does not have any idea about how things look, you have to draw "blindly" - as there's no visual feedback, the only feasible tactic is to first list things components each thing consists of (e.g. for a car wheels, windows, chassis, bumpers, lights, etc.) with as much accuracy as you can, establish some constraints (e.g. in a horse legs come out of the body, ears come out of the head, and so on), and then attempt to put all of it in a SVG. This is your task for now, and I will evaluate your drawings. Give me HTML code with embedded SVG that you drew and be verbose about both the things you're going to draw and the constraints.

The first thing you will draw is a unicorn.
