Yes, but it has nothing to do with biotech at all, except in the
presentation. The instructions say that the plaintext is represented
in the RGB values of each cell, along with the transparency (alpha) of
each color blob. So each character is represented (wolog, since we
don't know how deep the alpha channel is) by an integer value of ABGR
of each color blob.
Cute, but not biotech.
