A new line of "My Little Chromies" has been posted up by Khols. Just a Rainbow and Twilight model are available right now, but with some creativity you could probably morph them into whatever background pony clone you want if you are so inclined. The base set only includes the four marker colors you see above, along with a few stickers.
Get them over here.
Thanks to Rarity and Vane for sending them.
