what do you mean by a good intro can you rewrite it about the fair use i use the logo picture just in order to show the development link between the grand duc and neuron if you can design a dcg of the neuron scale model do it i used this one because as a correction since the previous pic was an outdated prototype namely the grand duc i have updated this article and i am responsible for the logiduc but i'm currently too busy to spend time on wiki so good luck
