Thanks to Cecilia de Groot for this video. I love how the morphs match the tempo. I can only guess this was created in Flash.
This reminds me of a music video that I just saw last week. The Japanese Popstars Feat. Green Velvet – Let Go. There’s also a “Making of..” video that I would recommend checking out. Apparently one of the animators who worked on this was also responsible for work done on Pink Floyd’s “The Wall“.
