There are some. I think there are a few in the market. I don't know if they are free or if they cost anything. Another option is if you are rooted. A lot of the newer roms have that live wallpaper included. Plus some roms have that wallpaper plus the options to customize it as well. If look around on other forums you will also find that live wallpaper as a download by itself so you don't have to change roms.
From my personal experience live wallpapers are a little over rated though. They look nice and is definitely a nice way to put any of your friends iPhones to shame haha, but it wastes your battery. I used them for a little when I originally downloaded a stable 2.1 rom but I haven't used them since because I saw how much faster it drained my battery.
If you have rom manager, almost all of those roms that you can install have that wallpaper built into it.
Hope that helped. Good luck bro.
