Sesame Street Background Tests October 5, 2015 For some reason, this one reminded me of 2001 A Space Odyssey. I was most fond of this 'tube design' and thought it could have had some real fun animations. Another mostly primary color attempt. I was told the tools were a big no-no. This style always seemed too adult, but also thought it could have some great looking animation loops floating around. Some unused style tests for a Sesame Street segment, The Letter D.
