"Spark" might be putting too fine a point on it if I am being honest (and I always am, ha ha).

But I vibe-coded a web site [1] that I would not have otherwise attempted (I just didn't want to have to figure out how to learn a map-type framework in order to put little points-of-interest on a web page.)

I also vote-coded an extremely esoteric app for turning .mpo files into stereograms that you can then print to display in an old-fashioned stereoscope [2].

I have lately been learning (I hope?) to build a hobbyist analog computer. This a deep dive into electronics—something I have no training in.

And I have already queued up a couple of my abandoned projects (also esoteric) that I hope to turn an LLM loose on when I free up some time (from my current analog computing obsession).

It's hard to say if I would not have pursued all the above without an LLM. I am giving examples though of projects that I feel were sort of on the tipping point for me as to whether they were worth the effort to pursue or not—the learning-curve-required vs. useful-end-product balance. I am finding the LLMs are a finger on the scale tipping it more often toward "Go for it." Maybe you would call that a "spark"?
