A bit off topic, but I noticed get this weird feeling when my cursor changes style. Something between a "let go of [free] my cursor" and "I wonder what secondary state I accidentally activated". It creates a weird sense of distress. Might just be me.

Though I did find it cool how it inverts the underlying thing. I thought it was a text-clipping type css property but it seems to invert media too? Any ideas how thats done?
