People feel time flows in different speeds under different situation. For instance when I am reading a comic I really like or making projects, time goes so fast that I don’t even feel it moves so fast. On the other hand, when I am doing plank or walking under a severe weather. Time goes so slow that I can feel each miili second flows. To emphasize this feeling, I decided to go with the idea non linear clock and visualize this idea through mapping the daily schedule to the clock speed.
Elliptic and functional gears play a crucial role in varying the time's speed.
Using a mechanism similar to certain city bikes, it involves two pulleys connected by a belt. Here's an introductory example and an interesting LEGO rendition. Another variant of CVT can be seen here.
