Given a fractal F, the Inverse problem is to find affine
transformations T_{1}, ..., T_{n} for which 
F = T_{1}(F) ∪ ... ∪ T_{n}(F) 
Here we present a method to solve this problem, as well as two implementations of the method. 
 Solving the inverse problem takes just two steps.

 Two implementations of Step 2, one
lowtech, one hightech.

 Examples and
practice problems

 When the pieces are not scaled by such obvious amounts, we can find scalings
and rotations by measuring distances and angles.

 Examples of finding IFS rules for natural fractals.
Some are simple, others require some new tricks.

 The relations between the parts of an IFS image can be effectively
revealed through some animations.
