I shortened my Aalaxy Anatomy software into a second software named Galaxy ABC.
ABC can be played even by a one-year-old baby. Rotate image, change image, change resolution, etc. Whatever baby's action, no bug would result in.
The Anatomy software is an advanced research one. The customer can borrow new galaxy image data from other people for its anatomy, can save screen result for academic publication, etc. It is for any serious person at least 5 years old.
