This one took quite a while. I had to get the frames from the episode (Feeling Pinkie Keen, if you're curious) and edit out the background for each frame, then resize all the images and make sure it loops correctly.
This one looks like the normal Windows startup logo, but then something happens and it seems Derpy might be responsible...
You'll have to watch the video to get the full idea. [link] The logo gets pretty washed out, unfortunately. But, that's all the more reason for you to download the zip and try it yourself.
Thanks for this awesome theme man.
Nice touch xD
Yeah yeah, you're a good pegasus, Derpy...
