Little something I threw together in over a week or two. Was supposed to be based on a mixture of DJ Sona's Kinetic skin and Vinyl's product placement car at the end of Rainbow Rocks. At first I was going to try animating it in AE, using the same pluggins the LoL team uses to make theres, but I figured I might as well save it for pixels. This is still however, animated at 30 fps for a 130 BPM song.

How to replace your LoL Login Screen with this animation:
1. Go to C:\Riot Games\League of Legends\RADS\projects\lol_air_client\releases\0.0.1.157\deploy\mod\lgn\themes

2. Click on the most recent login theme.

3. Go to the flv folder. Delete everything, replace it with the flv file in this download link. Make sure it's named: login-loop

4. Go into the music folder next and delete the two files in it. Copy in DJ Sona's Kinetic song twice, and rename them: "LoginScreenIntro" and "LoginScreenLoop". Just like how the two files you deleted were named.

5. Restart the client and it should hopefully work.

It worked for me at least. http://i.imgur.com/qf1APqV.jpg
