A.R.T.'s sibling organization, Jackfruit Research and Design, has worked on a digital resource on Nataraja, specifically one housed in the Freer and Sackler Galleries of Art, The Smithsonian Institution's Asian Museums of Art located in Washington D.C. We designed the information architecture, composed the content and wrote the text. It has finally gone live (after two years!). I am happy to share this with you and request your feedback.
