In this After Effects video tutorial, we turn the wall of a bathroom into a huge tetris game. For this funny effect, we use mocha to track the wall and Beat Assistant, KeyTweak and iExpressions to create and animate the Tetris bricks inside After Effects.

The second part covers all the animation done in AE. In particular

• creating blocky movements with the Snap To Grid iExpression
• make the blocks move to the beat of the music with Beat Assistant
• modify hundreds of keyframes simultaneously with KeyTweak
• make a sound repeat in an infinite loop with Beat Assistant
