You should tell me about stuff like this!
It looks like ponyville has been built from the ground up over on Second Life. I've never been a fan of the game, but this is REALLY tempting (Client already downloading doh!)
But what would Second Life be without Ponies? Apparently, these templates are relatively easy to customize as you see fit.
Yes, that is in fact Twilight Sparkle with a umbrella hat on the left. Some of it is still a work in progress, but it looks like they have made leaps and bounds in terms of progress. Connection instructions and more images can be found after the break!
In order to join up over here, you need to do a few things! Right now my client is still downloading, and I have to leave for work, so I won't be able to test all of this, but these are the general instructions I was given for connecting and making my own pony.
1.) Download the Second Life Client found here! It's all free!
2.) Go through the orientation once everything is installed and ready, you can skip it, but might as well!
3.) Use the search bar to look for "bronyville", and click "teleport".
4.) Someone named Twinkie Swizzle (The Creator) should be able to get you your very own pony avatar. From there you can customize it as you see fit.
That's the basics. As I said, I haven't tested it yet, but hopefully it all works out.
Have some more images!
Cloudsdale is still being built, so that isn't it's complete state.
