Heart

As discussed with Rosie, my original idea was to have three separate clips on three different screens interacting with each other. Once I had the finger animation completed, I had thought of ways to have the detached finger interact with another clip which results in it morphing into another clip.

Wormhole

My first idea was to have the finger travel across two screens and penetrate into a wormhole, which would then implode and morph into the mouth chin. 

Using this online tutorial, I was able to create a simple scribble effect in which I combined an extra animation of the detached finger being sucked into the wormhole.

The above video is what it would have looked like with the three screens. However, I wasn't entirely happy with the outcome, as it looked too flat and linear for my liking. I wanted to create something which was a bit more dynamic, therefore I decided to focus on just one screen.

Shockwave

After ditching the wormhole, I wanted to create something similar to it but more technical and fluid. I found a tutorial on how to create a shockwave effect through After Effects. This had a smokey and electrical style to it. Again, I wasn't too happy with the outcome as it just felt too out of place with the rest of the project.

After taking a break on this part of the project and focusing on other clips, I came up with an idea of having the finger burst into a heart, before morphing into the mouth/eye chin. The design heart itself was created on impulse whilst watching The Lego Movie (Below video at 1:41). I noticed a couple of floating flames in the background of a scene which gave me the idea of how the heart would be animated.

To begin with, I used the shape of a Lego fire piece as a template to start the animation with. 

By moving the individual parts subtly, I was able to create an almost plant-like effect. 

Originally, I decided to create a heart that resembles a sun. This was done by layering all of the compositions on top of each other. However, I wasn't happy with the outcome as it looked too obvious and some of the lines were overlapping others which didn't seem visually appealing.

I went back to the drawing board to try and come up with a new appearance for the heart. Looking at other animations for research, I managed to find the type of heart I was looking to create. 

The heart I designed featured a sort of tentacle/vine appearance. After animated the individual pieces, I placed them all together in order to create the shape of a heart. The way in which the small vines animate collectively look as if it is a beating heart.

Once I was happy with the outcome, I changed the colour of the heart to red. In addition, I added a darker shade running through the middle so it would add emphasis to its tangled look.

Finally, I added a Body to the background.
