Animate.css: Seamless CSS Animations Across All Browsers

That's quite a license. This is effectively unlicensed and unusable. I applaud the effort, but the terms are too vague. If I accidentally violate the terms of this license there is no period to cure or remedy the violation, for instance.

I am actually looking for something very similar to this for a project I'm working on right now. However the license is something that would not be compatible with almost anything I would ever release or work on. I can't release a project in any license I want because this license is incompatible with it, and likewise any company I work with can't use a license that has this vague interpretation.

I've almost used these in projects many times when I wanted to add basic animations quickly. Credits to the authors for making a library with a nice CSS API, good docs, and a nice demo website.

... but I've always found the defaults too loud for my taste. Kind of like most Power Point animations --- only usable now to be satirical or intentionally corny. That, and the provided animation flavors are never quite what I want. Once I consider considering customizing them, I decide to just go with something else.
