I could see it being a real thing. When you’re making a game it gives you visualization for animations (both physics and visual-only) and shaders (maybe even a simplified stylized version). Random benchmark results/debug info. Drawing attention to syntax mistakes. An important email or video call pops up.

It would be cool and potentially useful, but completely un-asked for and likely distracting and a waste of space. Basically what if your computer was a non-cartoon clippy.
