>>What's your view on this? I see that this starting to take place now. I 've seen some GFP Axolotls, and can help but wonder when we will have a glow in the dark Gartersnake or a green snake given a growth gene from a retic. I am considering experimenting with it myself. You can purchase most of what is need for such experiments from online biological supply companies for a few hundred dollars.
I want a genetically engineered mini-Trex that stands about 1' high and can be trained to attack the neighborhood kids. 
genetic engineering isn't nearly as far along as that. There's been some good work with implants (growing human organs on lab mice for instance) but I'm unaware of anything that would come remotely close to what you're talking about with the 2nd example. I've seen glow-in-the dark fish (BLECH) but I think those have mostly been done by injecting chemicals into translucent fish, rather than actual genetic engineering. There's been cloning of course, and there's been cases where single, simple traits are altered (receptors for certain biological or chemical signals)but I haven't seen anything done that substantially reworks an animal.
Personally, they wouldn't be "herps" at that point, just oddities. Neat ones maybe though.
