He spent his professional life studying turbulent flow and mixing phenomena. I helped with some of his flow visualization studies in his lab. The collection of pictures on the right are from the eFluids Gallery of Images. They are similar to some of the flow visualization experiments that he worked on. I love the patterns that the eddies form along the boundary layer between two different materials.
His other passion is Native American art. He has collected artwork for more than 40 years and donated much of his pottery collection to the Heard Museum. Pieces from the Neil and Sarah Berman collection have been included in museum exhibits around the world. He has been a friend to many artists over the years and currently volunteers at the Heard Museum. He enjoys collecting fetishes and has given us a number of them. The Zuni associate the white bear with healing. The bears come in various shapes as shown in the pictures on the left. Many of them have life lines made out of colored stone and carry bundles of gifts.
I am planning on combining a medicine bear with one of the flow visualization patterns in my TIF challenge piece. I have not decided whether I will include the pattern inside the bear or surround a white bear with one of the patterns. I also have not decided what colors to use. I don't think that I will use blue or green for my father -- he is color blind and can't see them. I have thought about adobe or sandstone colors from the desert or tennis ball yellow.
