Just so we're clear, this is ONE pixel per, I don't know, 10000 cells or so. So one bit per DNA chain, with that bit repeated thousands of times to get redundancy. Still and incredible achievement.
The super neat thing is that they tag each DNA chain with the pixel coordinates, so you can afterwards mix those 10,000 DNA strands each for all 96 pixels into one 1-mio-DNA-strand-soup and still recover the image successfully.
