In a quest to erase the superficial differences between myself and Draygone, I have allowed myself to become interested in changing to other avatars. And this thing was near the top of the list. It's an Isle of Wyrms avatar.
At L$3500, it is one of the most expensive avatars in SL, and for good reason. The animations are fluid, the wings are functional and not stiff, and it comes with a couple HUDs featuring animations and a texture editor, with LOTS of textures to choose from (the bird's default fur/feathers are more typical to a gryphon).
This picture was taken at my home, but I've got links to my home in other pictures, so I shall instead supply the SLurl to where I found this avatar. There's also a much cheaper gryphon hatchling available, but this avatar looks much more awesome.
