inflection mapping gadget for complex quadratic polynomials
you probably want at least 0.3.2, it combines the features of 0.1 and 0.2, and adds more goodies. 0.4 adds variable sized inflection discs.
this documentation is for inflector-gadget 0.4
You can generate animations interpolating between keyframes, provided that all the keyframes have the same number of inflection discs. If you try to interpolate between keyframes with different numbers of inflection discs, unpredictable results are to be expected. Possibly it will get stuck in places or otherwise not do what you want.
(This tutorial was made with 0.3.1, in 0.4 you need to drag the inflection disc rather than just clicking.)
On first load you should see this:
Left-click near the top and you get something like this:
