CTRL-Z
This was a small personal project that was born out of a very simple idea. How far can the ctrl-z (probably the most used short-cut ever) effect go? Could it go all the way back to when the idea was first born?
A part that took a little while to get right was the smoke simulation. It need to look like vapor coming out of a tea or coffee, which took some trial and error to get to a good balance.
Once the main scene was done, it was an easier process to make it look "less done" as we went back in time in the animation.
The final version :)
