This is so funny - I just recently realized myself that it is the machines that I love - truly machine lust. There is something so soothing about hearing them run and I too love learning the techniques and understanding the capabilities of the machines. One of these days I will probably make something successfully (I hope) but I am enjoying have all the tools and capabilities! My father and brother are both engineers, so maybe there's an engineering gene in your family too -it must make us attracted to the machines!
