I have in my head, but have not written down, a sci fi story similar to that- "diybio" where some smart grad students clone cephalopod camoflague genes and make a crispr delivery system to give people the ability to grow moving tattoos that glow (go look at a cuttlefish). They go to burning man and give it away- massive night raves with people dancing around, etc.

based on those good results, they go back to the lab and cook up a general purpose "edit your own genome for free!" project and put all the steps to reproduce it in a github repo. But... after half the world has downloaded and started playing, those burning man people start dying of cancer.
