How did this happen ?

I was casually procrastinating in Second life, when I discovered you can combine a dance animation with the bang animation in the game. Second life actually allow everyone to upload anything in the game and have its own scriting system, that's why you find this kind of things. So I decided to record it and make an animated gif out of it, and grabed the first record software I found. When I watched the final result all the videos had weird time distorsions and since I was kind of high, it inspired me and... This happened !
