Not even a sample "Hello world"?

I'd like to see a sample of the language, too. However, whereas "Hello, World" is an example of a simple function to give a taste of a language syntax, I would suspect that getting bacteria to spell out "Hello, World", or produce DNA strands that would fold up into the letters, would be kind of the opposite of simple. =)
Maybe future bioprogrammers can come up with a simple protein that doesn't exist in nature (and would be easily broken down/inert. No new prion disease, please) that could be the biological equivalent of "Hello"?

Maybe a "hello world" could be choice of color and intensity of bioluminescence.

blum(blue,5);
blum(red,255);
blum(green,1200);

Using this language, the researchers programmed 60 circuits with different functions, and 45 of them worked correctly the first time they were tested.

So, there were bugs in their bugs.

April 1st joke?

It looks like assembler and it's called CELLO (not to be confused with the homonymous library for C).

Neat.

I have already some useful ideas for yeasts, would be awesome if you could make them stop reproducing when a certain batch of beer reaches a given amount of alcohol.

It'd be interesting to "reverse compile" the human DNA sequence, and see what comes out. Could give some clue to the significance of "junk" human DNA sequences, amongst other things.
