It is well-said that a picture is worth a thousand words. I have always found that a good, illustrative graphic can make a great impact upon the understanding of complex cellular pathways. And when one is visualizing dynamic processes, such as the processes occurring within the physiological system, newer technologies such as animations can be of a tremendous help. Of course, in order to be useful, it must be well-researched (so as to be scientifically accurate) as well as well-executed. This is why I was so excited about an animation depicting an immune process in the mammalian intestines presented by Nature Immunology.
