I retired from being a Head & Neck/Skin cancer nurse over 4 years ago. On a Friday morning we would have a meeting to discuss cases and look at the cells under a microscope that would be shown on a large screen. The cells would be stained pink and this wall art took me back in an abstract kind of way. This looks similar to the top layer being skin with hair follicles beneath.
@wakelys reminded me of a stained slide too!
