Knife Party - Centipede [Osu!]

This is a fake Osu! gameplay created with visual effects. My right hand and the pen is a 3D models. Those 3D models use an inverse kinematic armature with the controller on the tip of the pen. The location of the tip of the pen is parented to the location of the Osu! cursor when running automated play. My left hand is real gameplay but played back 10 times faster.
