“On a continuous curve without tangents, constructible from elementary geometry” – Helge von Koch, 1904, fractal snowflake. Image: Koch_snowflake_(RGB-CMY).jpg. This work has been released into the public domain by its author, Solkoll. This applies worldwide. Re: fractal dimensions, if an object is transformed into N self-similar pieces and the ratio of the length of each piece to the length of the original object is r, and the subdivisions can be done infinitely many times, then the dimension is = log(N)/log(1/r).
