Animista lets people that write HTML/CSS/webapps interactively choose or tune the settings of a relatively small set of CSS animations styles. It's like a convenience table of contents for what one would typically find in scattered various CodePen examples. It wouldn't make much money.
It's a matter of value. There is nothing near 150k/mo of recurring revenue or sustainable value here.
Edit: And even though it's not what I was saying, I don't know why you think that kind of thinking is 'programmer think'. That's a bit disparaging to programmers, no? The ones I know aren't that shallow.
