Which picture was created using DNA origami recently?

Caltech scientists have made the world's smallest recreation of Leonardo da Vinci's Mona Lisa, the size of a bacterium, out of DNA. The technique, dubbed DNA origami, enabled scientists to fold DNA into desired self-assembling structures using 64 tiles, which were 100 nanometers wide. The team also created a life-sized portrait of a bacterium and a bacterium-sized portrait of a rooster.
