Glowing cats - where is the line drawn?

Korea is making glow in the dark cats! Should we be excited, scared or both? Is genetic manipulation going too far?

Modifying E. coli to smell like mint or bananas seems harmless, even useful. The economist claims that increasing field yields through genetic manipulation is the key to ending the food crisis.

Yet, where is the line? IS there a line? Will we be soon making birds that can sing for real or monkeys that talk or fish that can live out of the water? Will we design human beings or even new life forms?

Why am I surprised, aren't we already doing that? After all, cats that glow or e. coli that smells like banana have never before existed in nature...

Some claim the line is drawn on a physical term (like, when you make a pig with a human arm sticking out). I think that's just a temporary line. Once we get used to the idea, the line will be pushed further and further.

In my opinion, the real line will be drawn by nature coming back and chasing us for playing with something we have no idea about. The potential side effects of playing with the code of nature will be line.
