I have managed to port the Android Wear boot animation from the LG G Watch system dump to the Motorola MotoACTV succesfully and I think it looks really nice. It is running at the same 30fps as it is designed to on the G Watch which looks a lot nicer than the 15fps stock animation. Obviously you still have the Moto logo on the bootloader but I may try and swap that for something neater too at some point. Anyway enough talk, below is link to a video of it in action!
I have attached the bootanimation.zip for other people who want to try it out and I'll add instructions on how to install it for those unsure a bit later on.
Update! - New version with more optimised frames for a smaller filesize and an even smoother animation on the device. Grab the replaced attachment! Also I have created a preview gif as you can see below. The video is still nice to look at to see how it actually performs during the boot but this gif gives a clearer view of the actual animation.
Update 2: - New PNG version! JPG version normally works better on this device though. See post #11
