What sorts of problems can fractals solve? After doing a bit of research on fractals, I was wondering what sort of real-life applications do fractal have and in what way would they be used to help solve a problem. I already know people use fractals to map coastlines and borders, but is there any other 'smaller' problems that could be solved by using the principle of fractals and what would be some examples of these and how do they work?

Also, is there a way to generate a problem of a certain situation that could be solved by a fractal or its principles?
Fractals are used in many computer games to render realistic graphics for mountains, landscapes &amp; 3D terrains, especially for flight simulations, computer games, digital artworks &amp; animations. Rather than storing a huge amount of detailed height data in the computers memory, fractal-based algorithms generate the data 'on-the-fly' to render realistic landscapes in real-time. Algorithms for generating fractal-based landscapes take advantage of the 'self-similarity' which exist in the natural world to render visually rich and complex images with attention to fine detail at all scales to appear smooth and not suffer from 'pixelation' even when zooming in close. 

These algorithms use methods such as recursive subdivision and fractional Brownian motion to generate a 3D landscape which is then smoothed using a variety of techniques such as image filtering and polynomial interpolation (splines &amp; Bezier curves) to generate photorealistic images of rolling hills &amp; other natural scenes. 

Pioneers in this field include Ken Musgrave, digital artist and CEO of Pandromeda (http://www.pandromeda.com/) and  Loren Carpenter who went on to form Pixar Studios.
Not clear of what you mean by 'smaller' problems but anyway I suppose you should take a glance of the journals 'Fractals' and 'Chaos, Solitons &amp; Fractals'.
