It's not possible to smoothly move your eyes unless you are tracking a moving object. Your eyes always move in saccades (quick jerky movements), unless there is a smoothly moving object, in which case your eyes gain the ability to track it smoothly.
This is a good idea, but also the behavior will probably be emergent with the introduction of this feature - I can definitely see OSS maintainers offering logos/links in the README in exchange for monthly sponsorship. I bet we'll see the emergence of "Gold/Silver/Bronze" tiers too, just like at conferences.
Would love to check out /docs but it's currently a 404.
