Even though I cannot partake (alas my setup is iOS only) I was sent this clever boot animation by a friend.
The list of heroes (and villains) spans both the Marvel and DC universes. Christian Tailor is the artist and you can see more of his work on his website.

Christian works as a motion Graphic Designer specializing in information graphics, and his current clients include Al Jazeera and UK-based TV network ITV. The animation above is one of Christians’ spare time projects, and a pretty great one at that, if you ask me.

Graphic designer and Android theme maker Brian Roberts took Christian’s animation and turned it into a boot animation you can use to replace the default startup animation on your device.

And then Ronald Valdes turned it into a flashable zip you can download from here.
