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.
