This project is part of my Physics notes, and it is about observing rain drops in different directions. The concept comes from my lecturer Dr. Kim-vy Tran and she mentioned this example to describe why rain falls is a anisotropic and homogeneous medium.

The trick to realise that theory is that we see rain at an altitude and so I decided to draw two young kids while they see the rain drops at different directions. 

You can see there are arrows representing the direction of the rain drops. Each observer sees the rain drops either coming down to him (left), or coming down from the other guy (right). 

This the sketch of the characters.

Here's the snapshot in my notes, my notes are written in LaTeX

Thanks for watching, see you next time~
