I have found the artwork of Alex Grey to be helpful in my Giant Body visualizations. He has a number of paintings of luminous, transparent, anatomically correct human bodies, which I sometimes gaze at for awhile before starting my Giant Body practices. He doesn’t get down to the molecular or atomic levels, but his images do provide a good starting point for me. Here is one of his paintings which I have as a poster and which I use when I practice:
