I remember fondly of a raster talk at FOSDEM about 20 years ago: playing videos inside a terminal. Amazing!

Wow, I think I remember that talk, too. And I remember thinking, "why would anyone want to run a video inside a terminal?!" I still don't want to do that, but it was cool that enabling that feature only required a few lines of code, since EFL(?) already supported it, was already linked in, and the code to start it was minimal.
